Answer 1

Casey sold 22 tubs of cookie dough

Explanation:

Casey sold "k" cookies.

Her sister, Bozo, sold 3 times as many. So Bozo sold "3k" cookies

Together they sold 88. So we can write their sum as 88.

k + 3k = 88

we do algebra and solve for k:

k + 3k = 88

4k = 88

k = 88/4 = 22

Casey sold 22 cookies
