Question

Shelly is going shopping at the mall to buy 3 pairs of shoes. She has a coupon for $2 off perpair of shoe after buying the first pair at full price. Shelly is willing to spend $80 to $113 not including tax. If the shoes she purchases are all the same price, what is the least and most amount she can spend per pair?

Answer 1

$42

Explanation:

If you want to check, simply take the values I calculated, multiply them by 3 and subtract them by 2 for the second and third pair, they will add up to the values that Shelly is willing to purchase, excluding tax.
