Question

If a recipe that yields 80 servings calls for one pound of flour, what is the amount of flour needed when converting the recipe to yield 360 servings?

A) 1.8 pounds
B) 4.5 pounds
C) 2.25 pounds
D) 5.4 pounds

Answer 1

To determine the amount of flour needed for 360 servings when the original recipe yields 80 servings, we multiply 1 pound by 4.5, resulting in 4.5 pounds of flour.

Step-by-step explanation:

If a recipe that yields 80 servings calls for one pound of flour, to calculate the amount of flour needed for 360 servings, we can set up a proportion. Since the number of servings increases by a factor of 360/80, which simplifies to 4.5, we multiply the original amount of flour (1 pound) by this factor.

The calculation will be: 1 pound × 4.5 = 4.5 pounds of flour.
