Answer:
$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
