Question

Donte bought a computer that was 15% off the regular price of $780. If 7.5% sales tax was added to the sale price of the computer, what was the total price Donte paid for it?

Answer 1

$712.72

780×0.15

117

780−117

663

663×0.075

49.725

49.725+663

712.72

Answer 2

Price = 780
Discount = 15%
Tax = 7.5%

Price after tax = price + 7.5/100 price
= 780 + 7.5/100 * 780
= 780 + 58.5
= 838.5
Price = 838.5

Price after discount = 838.5 - 15/100 * 780
= 838.5 - 117
= 721.5
