Kasey and her sister both sold cookie dough. her sister sold three times as many tubs of cookie dough. if they sold a total of 88 tubs of cookie dough, then how many tubs of cookoe dough did kasey sell, k?

X= number of tubs Kasey sold
3x= number tubs sister sold

Add the number sold by Kasey and her sister to equal the total sold (88).

x + 3x= 88
combine like terms

4x= 88
divide both sides by 4

x= 22 number tubs Kasey sold

Number Sold by Sister
3x= 3(22)= 66

CHECK:
x + 3x= 88
22 + 3(22)= 88
22 + 66= 88
88= 88

ANSWER: Kasey sold 22 tubs and her sister sold 66 tubs.
