Question

Keylei’s family recipe for sugar cookies requires 1 1/2 cups of sugar for a batch of 30 cookies. Calculate the amount of sugar she needs for 1 cookie. Write an equation that represents the relationship between c cookies and s cups of sugar.

Answer 1

1 cookie = 0.05 cups of sugar, Equation: s = 0.05c

Explanation:

1 1/2 can simplify to 1.5

1.5/30 = 0.05

This means 0.05 cups of sugar is needed for 1 cookie

The equation would be s = 0.05c because the 0.05 of the cookies will be sugar.
