A grade six class is having a fundraiser. The class boys have three bags of apples. Each bag has 24 apples. The total cost of the three bags of apples is $12.24. The class sells the apples for 0.75 each.

How much will the class gain per apple?

3 * 24 = 72

12.24/72 = 0.17

0.75 - 0.17 = $_______ gain per apple

16.32

To find out how much the class will gain per apple, we need to calculate the profit.

First, let's determine the total cost of the three bags of apples. Since the total cost is $12.24 and there are three bags, we can divide the total cost by 3:
$12.24 ÷ 3 = $4.08 (cost per bag)

Next, let's find the cost per apple in each bag. If there are 24 apples in each bag and the cost per bag is $4.08, we can divide the cost per bag by the number of apples:
$4.08 ÷ 24 = $0.17 (cost per apple)

Now, let's calculate the profit per apple. The selling price per apple is $0.75, so we subtract the cost per apple from the selling price:
$0.75 - $0.17 = $0.58 (profit per apple)

Therefore, the class will gain $0.58 per apple.
