monica sold 3 pairs of her old slick sprinter sneakers at the re - laced secondhand store. before she left, monica spent $13 of her earnings on a used pair of boots. she had $8 remaining. how much did monica receive for each pair of sneakers?

Answer

Explanation:

Step1: Find total earnings

Let the total earnings be $x$. She spent $13$ dollars and had $8$ dollars remaining. So $x- 13=8$. Then $x=8 + 13$. $x=21$

Step2: Find earnings per - pair

She sold 3 pairs of sneakers. Let the earnings per pair be $y$. Then $3y=21$. So $y=\frac{21}{3}$. $y = 7$

Answer:

$7$
