Answer:
Discounted price of shirt = $14.4
Regular price of hat = $22.5
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
