2. Burnaby Farms wants to estimate the cost of fertilizing their fields for the coming year. Each hectare of cultivated land requires 15kg and they intend to work 300 hectares.

IPO Chart Input  

Processing

Cost per hectare [input] Cost of fertilizer [input]

Assumptions:  Number of hectares  Cost for total area

Output TotalCost [input]

Algorithm:  Cost of fertilizer  Cost per hectare unknown

Sample Calculation / Desk-Checking Table Landarea [input]

Missing?

Costperhectre Costperfertilizer Missing?

Not solvable – Burnaby farms hasn’t listed the cost of the fertilizer for the land. All we know is the total hectares need to be fertilized is 300 and each hectare requires fertilizes is 15kg. Total fertilizer needed (kg) for the 300 hectares is expressed 300*15 = 4500kg.

3. Cherry Entertainment Corp. is looking into the profitability of hosting MMA XXII at the Rogers Center. The sale of tickets, broadcasting rights and advertising will gross approximately $2 million. How much profit will Cherry Entertainment Center make if Rogers Centre cost $800, 000?

IPO Chart Input  

Processing

Gross Profit [input] Cost Rental

Assumptions:  Gross revenue  Cost of rental

Output Total Revenue [input]

Algorithm: 1. Enter Total revenue; 2. Enter Cost Rental; 3. Subtract Total Revenue - from Cost Rental 4. Display Profit

Sample Calculation / Desk-Checking Table Gross profit [input]

Cost rental [input]

Total Revenue [input]

1,200,000

$800,000

2,000,000

Solvable - You need to subtract total revenue (2million) from the cost of renting Rogers Centre (800k) to get the gross profit which is 1.2million. 1, 200, 000 - 800,000 = 2,000,000

5. Estelle’s Grocery is having a back-to-school sale of up to 50% off on most food items. The price of potatoes is 11₵ per kg. A plastic bag costs 5₵. What will the total cost (potatoes and bag) if someone buys 25kg of potatoes? IPO Chart Input   

Discountonfood[input] Priceofpotatos Costplasticbag

Processing

Output

Assumptions: 1. 1 plastic bag can contain 25kg 2. 50% discount on most food items Algorithm 1. Enter price of potatoes 2. Enter price of plastic bag 3. Enter quantity of potatoes 4. Enter bag capacity 5. Calculate cost of potatoes price of potatoes after discount multiply number of potatoes bought= 6. Calculate total cost = cost of potatoes + cost of bag 7. Display total cost

Total cost

Sample Calculation / Desk-Checking Table

Not solvable – Since this equation is missing information, it does not mention how much each bag can hold and how many plastics bags are given. Discount on food 0.11*0.5 = $0.055 Cost of potatoes (price after discount) = 0.055*25kg (total potatoes bought) = $ 1.375 Total Cost = .5 (Cost of plastic bag) + 1.375 = $1.38 0.11*25+0.05 = $2.80

6. Fancy Jewelers is located in the Scarborough Town Center on the second floor near to Wal-Mart. In their Boxing week sale earrings were priced at $20 per pair. If Narendra wants to get a pair for as many females in his family as he can. How many pairs can he get if he has $125? [You may assume that there are more females in his family than he can buy earrings.]

IPO Chart Input  

Processing

Price per earing [input] Budget[input]

Output

Assumptions: 1. Bought similar earrings 2. How many females in his family? Algorithm: 1. Enter price of earrings 2. Enter budget 3. Calculation number of earing by dividing budget/price of earrings 4. Display total pair of earrings

$125

6.25

This equation is solvable because all required information is available the answer is 6.25 and can only buy 6 pairs of earrings for the females in his family. You can’t buy a quarter of an earring they are not produced that way. I got 6 from dividing current budget of $125 by the price of the earing $20 this equals 6.25. 125/20 = 6.25 ~ Rounding to 6

IPO Chart Input    

Processing

Price per meter of pipe [input] Price of join Number of joins Length of pipe

Output

Assumptions 1. Installing the same type of pipe 2. Length of pipe is the same Algorithm: 1. Enter price per meter of pipe 2. Enter Price of join 3. Enter Number of joins 4. Enter Length of pipe 5. Calculate cost by a. multiplying price per meter pipe * length of pipe b. multiply price join x number of joins c. sum a + sum b 6. display total cost

Total cost

Sample Calculation / Desk-Checking Table Price per meter [input]

Number of joins [input]

Total Cost [output]

Length of pipe

Price of joins

Price per meter*length of pipe

Price of joins*number of joins

(Sum a) + (Sum b)

1.25*12=sum a (15)

.90*4= sum b (3.6)

$18.60

The total cost of pipe for 12 meters is $1.25/meter and 4 joins @ .90 cents/join equals $18.60 (4*.90) + (1.25*12) = 18.60

Solvable - This Equations is solvable considering each ride required a single ticket. When you add all the tickets used 15+12+10+9 the sum of tickets used on all rides is 46. When you subtract 46 from the total number of tickets bought (50). The tickets remaining equal 4. Simple Calculation 50 – 46 = 4
