1
2
cups of vegetable oil, how much will she have left over after she makes the cake pops and cupcakes?

1 answer

Stacy needs 2/1 * 1/2 = <<2/1*1/2=1/1>>1 cup of vegetable oil for the cupcakes.
So she needs a total of 1 + 1/2 = <<1+1/2=3/2>>3/2 cups of vegetable oil for the cake pops and cupcakes.
Stacy will have 2 1/2 - 3/2 = <<2 1/2-3/2=1/2>>1/2 cup of vegetable oil left over. Answer: \boxed{\frac{1}{2}}.
