After the 20% off discount is applied, what will be the discounted cost of the shoes (before tax)? Justify your answer using equations, models, and/or words to explain your mathematical reasoning.

Answer 1

a.
`Savings = \$16`

b.
`Price = \$96`

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`
