Excel Practice Exam This assignment has a total of 500 points. Complete the exam by placing all answers in the indicated cells. Do not insert rows or columns unless instructed to do so. The grader relies on the current worksheet structure. Amortization

You have decided to purchase a new car. You plan to take out a loan to pay for the car. The loan amount is $18,900. You will pay an interest rate of 6.5% and plan to pay off the car in 48 months. You want to calculate the total amount of money and the total amount of interest you will pay over the course of the loan. To help you with these calculations, you decide to construct an amortization table. An amortization table provides details about the payment, interest amount, principal amount, and loan balance for every month of the loan. Perform the tasks below to complete the amortization table and loan summary calculations. Task # Points

Task Description

1

34

Calculate the payment amount for the loan in cell C15. Reference the cells containing the appropriate loan information as the arguments for the function you use. Cells C20–C67 in the "Payment" column are populated with the payment amount from cell C15.

2

3

Calculate, in cell D20, the interest amount for period 1 by multiplying the balance in period 0 (cell F19) by the loan interest rate (cell C13) divided by 12. Dividing the interest rate by 12 results in the monthly interest rate. This formula is reusable. The interest for a given period is always the monthly interest rate times the balance from the previous period.

3

2

Copy the interest amount calculation down to complete the "Interest" column of the amortization table.

4

3

Calculate, in cell E20, the principal amount for period 1. The principal amount is the difference between the payment amount (cell C20) and the interest amount (cell D20) for period 1. Construct your formula in such a way that it can be reused to complete the "principal" column of the amortization table.

5

2

Copy the principal amount calculation down to complete the "principal" column of the amortization table.

6

3

Calculate, in cell F20, the balance for period 1. The balance is the difference between the balance for period 0 (cell F19) and the principal amount for period 1 (cell E20). This formula is reusable. The balance is always calculated as the difference between the balance from the previous period and the principal amount for the current period.

7

2

Copy the balance amount calculation down to complete the "Balance" column of the amortization table.

8

3

Calculate, in cell G12, the total amount paid by multiplying the payment amount (cell C15) by the term of the loan (cell C12).

9

34

Calculate the total interest paid in cell G13. The total interest paid is the sum of all interest paid in the "Interest" column of the amortization table.

10

34

Check to see if the total interest calculation in the amortization table is correct. The total interest paid is also equal to the difference between the total amount paid over the course of the loan and the original loan amount. Insert a formula into cell G14 to calculate the difference between the total amount paid and the original loan amount. Notice the negative sign associated with the original loan amount. This value should equal the total interest calculated using the amortization table.

11

1

Assume you have made the first 36 payments on your loan. You want to trade the car in for a new car. You believe that you can sell your car for $4000. Will this cover the balance remaining on the car in period 36? Answer either "Yes" or "No" in cell G15 from the drop-down menu.

Four J's Painting

Four J's Painting is a home painting contractor that completes interior painting work for new construction projects. Four J's Painting has four employees: Jim, Jill, Jake, and Jennifer. You have been hired to determine how the company can be more efficient and provide better service. You have tracked information on the last 20 painting projects in table 1. Employees receive bonuses for efficient and high-quality work. Occasionally, some jobs require additional work to correct flaws (touch-up work). Information about the projects that required touch-up work is stored in table 2. Table 3 summarizes information about the employees. Table 4 categorizes the projects according to difficulty. Complete tables 1 through 4 to determine how to more efficiently and effectively run the company. Complete each task so that the formulas you use can be copied and pasted down to complete the columns of the tables. Do not name your lookup tables; rather, you should keep them as references (e.g. B16:C30). Task # Points 1 2

Task Description

5

Use the HLOOKUP function to complete the "Hourly Wage" column of table 1. Use the "Employee" from table 1 as the lookup_value and the "Employee Wage Information" above table 1 as your reference table.

14

Use the AND function to complete the "Time Bonus?" column of table 1. An employee earns a time bonus if the project’s "Hours Worked" are fewer than the

"Estimated Hours" and if the work "Quality" is greater than 1.

3

14

Use the OR function to complete the "Outcome Bonus?" column of table 1. An employee earns an outcome bonus if the difficulty of a job is greater than 3 or if the quality of their work is equal to 3.

4

8

Use the IF function to complete the "Time Bonus $" column of table 1. If an employee earns a time bonus (i.e., the corresponding cell in the "Time Bonus?" column is TRUE), then "Time Bonus $" is the "Job Pay" for that project times the bonus percentage in cell M11. Otherwise "Time Bonus $" is 0.

5

8

Use the IF function to complete the "Outcome Bonus $" column of table 1. If an employee earns an outcome bonus (i.e., the corresponding cell in the "Outcome Bonus?" column is TRUE), then "Outcome Bonus $" is the "Job Pay" for that project times the outcome bonus percentage in cell M12; otherwise, "Outcome Bonus $" is 0.

6

10

Use the IF function to complete the "Comments" column of table 1. Display "Good Job" if both the "Hours Worked" are less than or equal to the "Estimated Hours" for a project and the assessed "Quality" of that project is greater than 1. Display "Too Much Time" if the "Hours Worked" on a project exceed the "Estimated Hours" for that project; otherwise, display "Poor Quality."

7

5

Use the VLOOKUP function to complete the "Employee" column of table 2. Use "Job ID" from table 2 as your lookup_value(s) and table 1 as the reference table.

8

5

Use the VLOOKUP function to complete the "Difficulty" column of table 2. Again, use "Job ID" from table 2 as the lookup_value(s) and table 1 as the reference table.

9

3

Use the COUNTIF function to complete the "# of Jobs" column in table 3. Reference the appropriate field in table 1 as your range and the "Employee" names in table 3 as your criteria.

10

3

Spending

You have created a worksheet ("Spending") to help you track your spending for the month of August. You are able to download your debit card transactions from your bank's website, but the information is not presented in a clear way. The transaction information includes a time stamp (a number that the bank associates with a specific date and time), merchant ID, and amount for each of the 63 transactions you made in August. You have decided to use what you know about how Excel handles dates, times, and text to reformat the information you received from your bank and make it easier to read and understand. Complete the table below by performing each of the tasks. In the rightmost column of the table, you will create a statement about each transaction. This statement follows the format

of the template in cell D9. Because there may be more than one way to complete each field of the table, use the functions suggested in each of the task descriptions. Task # Points

Event Profitability

You are the owner of a small business that manages the program, food, and merchandise sales at the Excel Center, where the local professional basketball team plays. In addition to basketball games, the Excel Center hosts dozens of events a year. Your company handles all sales made inside the arena. There are three major products you sell: programs, food, and merchandise. You have decided to build a spreadsheet model to help you analyze and project the profitability of future events. The "Event Profit" worksheet contains this model. You have randomly selected sales and attendance data from a number of past events to help build your model. This data can be found on the "Past Events" worksheet. You will analyze this data in order to obtain appropriate values to develop the model. Complete the tasks to finish the model. Whenever possible, reference cells rather than hard-coding values in the cells of your worksheet. Task # Points
