The recipe calls for 2 1/2 pounds of flour for every 1/4 cup of sugar.
To find out how many pounds of flour should Eric use for 1 cup of sugar, we can set up a proportion.
2 1/2 pounds of flour = 1/4 cup of sugar
x pounds of flour = 1 cup of sugar
Cross-multiplying, we get:
(x pounds of flour) * (1/4 cup of sugar) = (2 1/2 pounds of flour) * (1 cup of sugar)
x/4 = 2.5
Multiplying both sides by 4, we get:
x = 10
Therefore, Eric should use 10 pounds of flour for 1 cup of sugar.
