A 100-serving recipe contains 0.25 pounds of ground beef. If you adjust the recipe using a factor of 5, how many pounds of ground beef will be in the new batch?

• A. 0.75
• B. 5
• C. 1.25
• D. 2.5

Answer: (C)

Scaling a recipe means multiplying every ingredient by the same factor. If you’re increasing the batch by five, you multiply the original beef amount by five. The original amount is 0.25 pounds, and 0.25 × 5 = 1.25 pounds. So the new batch needs 1.25 pounds of ground beef. Other numbers would come from using a different multiplier, not five.
