Final answer:
By calculating the price per pound for both apples and oranges based on the store's special, we determine that apples at $0.70 per pound are a better value than oranges at $0.86 per pound.
Step-by-step explanation:
The question requires us to compare the price of apples and oranges on a per pound basis to determine which purchase is a better value. To do this, we calculate the price per pound for each fruit by dividing the total price by the number of pounds. For apples, the store's special is 4 pounds for $2.80, so we divide $2.80 by 4 to get the price per pound. Similarly, for oranges, the store's special is 3 pounds for $2.58, which we divide by 3 to get the price per pound of oranges.
Price per pound for apples: $2.80 / 4 pounds = $0.70 per pound
Price per pound for oranges: $2.58 / 3 pounds = $0.86 per pound
After calculation, we find that apples cost less per pound compared to oranges given the special prices.
