Question

Today, everything at a store is on sale. The store offers a 20% discount. The regular price of a T-shirt is $18. What is the discount price. Explain your reasoning.

Answer 1

Answer:

$22.50

Step-by-step explanation:

If $18 = 20% off, then that means $18 is 80% of the original price.

80% as a decimal = .8

($18) divided by (.8) equals ($22.50)

To check your answer,

$22.50 x .8 = $18

Discount price = 3.60

Step-by-step explanation:

discount price = 20/100 * 18 =1/5 * 18 = $ 3.60

Selling price  = 18-3.6 = $ 14.40
