Question

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

Answer 1

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
