Answer:
The cost of each pair of sneakers is $33.25.
Step-by-step explanation:
Consider the provided information.
Meryl spends a total $68.82 for 2 pairs of sneakers with the same cost.
If the sales tax is $5.32 and she also uses a coupon for $3.00 off her purchase.
First subtract the sales tax from the spend amount.
She use a coupon for $3.00 OFF.
$66.5 was the cost of 2 pairs of sneakers before using the coupon.
Now divide $66.5 by 2 so that we can find the cost of one pair of sneakers.
Hence, the cost of each pair of sneakers is $33.25.
