Answer:

Discounted price of shirt = $14.4

Regular price of hat = $22.5

Step-by-step explanation:

Given:

Discount = 20 % = 0.20

Regular price of shirt = $18

Discounted price of hat  = $18

Computation:

Discounted price = Regular price (1-Discount)

Discounted price of shirt = 18(1-0.20)

Discounted price of shirt = $14.4

Regular price of hat = 18[100/(100-20)]

Regular price of hat = $22.5
