Question

Mr. Ellis has a bakery and sells cookies. This week, he made 4 dozen chocolate chip cookies, 3 dozen oatmeal raisin cookies, and 5 dozen sugar cookies. He sold 135 cookies. How many cookies does Mr. Ellis have left? (One dozen = 12.)

Answer 1

Mr Ellis has 9 cookies left

Explanation:

12 × 4 = 48

12 × 3 = 36

12× 5 = 60

48+36+60= 144 cookies

144 - 135 = 9 cookies left
