Grandma Betty's recipe makes 6 cupcakes and uses of a cup of sugar. How many cups of sugar will it take to make 2 dozen cupcakes?
Let x be the amount of sugar, in cups needed to make dozen or 30 cupcakes. Using the ratio sugar/cupcake, we write the proportion:
Solve for x:
Multiply both sides by 30:
cups
So, the answer is choice A.
