professor190 [17]

Answer:

a. Savings =  \$16

b. Price = \$96

Step-by-step explanation:

Solving (a):

Price = \$80

Coupon = 20\%

Required

Determine her savings.

Savings = Coupon * Price

Savings = 20\% * \$80

Savings =  \$16

Solving (a):

Price = \$120

Coupon = 20\%

Required

Determine the price before tax

First, we need to determine her savings

Savings = Coupon * Price

Savings = 20\% * \$120

Savings =  \$24

The price before tax is calculated as follows:

Price = \$120 - \$24

Price = \$96
