The correct response is D. Multiply 0.89 by 3; subtract the product from $7.15; divide the difference by 4.
This sequence of operations is used to find the cost of each apple. By multiplying 0.89 by 3, we find the total cost of the oranges (because there are 3 of them). Then, we subtract this amount from $7.15 to find the cost of the apples. Finally, we divide the difference by 4 to find the cost of each apple.
