Question

Torrey has $20 to buy a birthday present for her that she does this to buy a CD for $18 the sales tax is 7% does she have enough money explain the reason

Answer 1

No, because she will go over by .57 cents. So she won't be able to buy the gift. You can find the answer by dividing 18 by 7 and adding that answer to 18 to get the amount total you owe including tax.
