Answer: v=-81.92

Step-by-step explanation:

$\displaystyle\\7+\frac{v}{8} =-3.24\\\\7+\frac{v}{8}-7 =-3.24-7\\\\\frac{v}{8} =-10.24\\\\\frac{v}{8} =-10.24$

Multiply both parts of the equation by 8:

$\displaystyle\\(\frac{v}{8})(8)=(-10.24)(8) \\\\v=-81.92$

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 8

Rufina [12.5K]

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.
