Eric is baking a cake. The recipe calls for 2 and 1/2 pounds of flour for every 1/4 cup of sugar. How many pounds of flour should Eric use for 1 cup of sugar?
A. 1/10
B. 5/8
C. 4
D. 10
To find how many pounds of flour should Eric use for 1 cup of sugar, we need to convert the units so that they match.
1/4 cup of sugar is equivalent to 2 and 1/2 pounds of flour.
Therefore, 1 cup of sugar is equivalent to 4 * (2 and 1/2) pounds of flour (since 1 cup is 4 times the amount of 1/4 cup).
Simplifying, we have 4 * (2 and 1/2) pounds of flour = 10 pounds of flour.
Thus, Eric should use 10 pounds of flour for 1 cup of sugar.
The answer is D. 10.
