Question

Eugene ate 20% of the Christmas cookies his

grandmother made. If he ate 8 cookies, how
many are left?

Answer 1

There are 32 cookies left

Explanation:

There are c cookies when we started

c* 20% = 8 cookies

Change to decimal form

c * .20 = 8

Divide each side by .2

c * .2 / .2 = 8/.2

c =40

There are 40 cookies when we started

40 -8 = 32

There are 32 cookies left
