Question

A sweater which originally cost $ 38.40 is on sale 25% off. Carmen has gift card worth $15 off, but the gift card can only be used if she pays the original price the sweater. The sales tax for the final amount, after the discount is taken, is 8%

Answer 1

If she goes with the 25% off she will have to pay 28.80

if she uses the $15 off she will have to pay
$35.33 plus the $15 off would be 20.33 so she's better off going through doing it this way rather than the 25% off
