Final answer:
To determine the cost per orange, divide the total cost of the bag by the number of oranges. A bag with 7 oranges costs $1.75, resulting in each orange costing 25 cents.
Step-by-step explanation:
To find the cost per orange, we divide the total cost of the bag by the number of oranges in that bag. The store sells a bag of 7 oranges for $1.75. So, we divide $1.75 by 7 to find the cost per orange.
Cost per orange = Total cost of the bag ÷ Number of oranges in the bag
Cost per orange = $1.75 ÷ 7 = $0.25 per orange
Therefore, each orange costs 25 cents when bought in a bag of 7 for $1.75.
