Jack bought a new suit that originally cost $176.85. He had a coupon for 30% off the original price. After using the coupon, he had to pay 6% in sales tax. How much total did Jack pay for the suit?

$134.40

Step-by-step explanation:

suit original cost = $176.85

coupon = 30% off

find 30%

10% = 17.69

17.69 × 3 = $53.07

$176.85 - $53.07 = $123.78

then we need to find 6% of $176.85

10% = 17.69 ÷ 2

5% = 8.85

1% = 1.77

8.85 + 1.77 = $10.62

then we add the 6% to $123.78

$123.78 + $10.62 = $134.40
