Find the final cost to the employer.

Original price: $129.00

Employee discount: 20%

Sale discount: 30%

Sales tax: 5%

a.$75.85

b.$70.95

c.$68.63

d.$67.72

e.$61.28

The correct answer is A) $75.85.

A discount of 20% means that the cost is 80% of the original. 80%=80/100=0.8

0.8 (129) = 103.20

A discount of 30% means that the cost is 70% of the amount before discount. 70%=70/100=0.7

0.7 (103.20) = 72.24

A sales tax of 5% means that it is 105% of the amount pre-tax. 105%=105/100=1.05

1.05 (72.24) ≈ 75.85
