Final answer:
Suzy needs to buy 2.5 pounds of apples for her pie, as 40 ounces is equivalent to 2.5 pounds using the conversion factor of 1 pound equals 16 ounces.
Step-by-step explanation:
The question you've asked is related to measurement conversion, specifically from ounces to pounds. To determine how many pounds Suzy needs to buy for her pie that requires 40 ounces of apples, we use the unit equivalence that 1 pound equals 16 ounces. To find the equivalent pounds, we divide the total number of ounces needed by the number of ounces in a pound.
So, we calculate 40 oz ÷ 16 oz/pound = 2.5 pounds.
Therefore, the correct answer is (A) 2.5 pounds.
