Answer 1

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:

$Price = \ 120 - \ 24$

$Price = \ 96$
