Answer:
7 1/2 cups
Step-by-step explanation:
Write and solve an equation of ratios to answer this question:
Sugar Cake weight
1 1/2 cups 3 lb
---------------- = -------------
x 5 lb
Then, after cross-multiplying, we get:
3x = (3/2)(5), or 3x = 15/2, or x = 7/2
A 5 lb cake requires 7/2 (or 7 1/2) cups of sugar.
