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?
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.
