Question

Max was assigned to make 64 cookies for the bake sale. He made 125% of that number. 90% of the cookies he made were sold. How many of Max's cookies were left after the bake sale?

Answer 1

Answer: there are 8 cookies left

Explanation:

Let's count how many cookies Max baked:

125% = 1.25

64 × 1.25 = 80

Let's count how many cookies were sold:

90% = 0.9

80 × 0.9 = 72

Leftover cookies:

80 - 72 = 8
