A recipe requires 2 lb of cleaned, prepared strawberries. If the yield from whole strawberries is 91%, how many pounds of whole strawberries must be ordered at minimum?

• A. 1.82
• B. 2.20
• C. 2.91
• D. 4.40

Answer: (B)

When a recipe uses cleaned product and you know the extraction yield, you divide the needed amount by the yield to find how much to purchase. You need 2 lb usable strawberries, and the yield from whole strawberries is 91% (0.91). So the amount to order is 2 ÷ 0.91 ≈ 2.198 lb. Rounding up to the nearest hundredth gives 2.20 lb, which ensures at least 2 lb after processing. The other options would either fall short after yield or exceed what’s needed, so 2.20 lb is the smallest amount that meets the requirement.
