Question

Today, everything at a store is on sale. The store offers a 20% discount.

PARTA
The regular price of a T-shirt is $18.
What is the discount price?

Answer 1

The discount price is $14.40.

Explanation:

convert percent to decimal (division of 100)

0.2 x 18 = 3.6

18 - 3.6 = 14.4

Answer 2

Answer: $14.40

10% of $18 = $1.80 (just divide it by 10)
$1.80 x 2 = $3.60
20% of $18 = $3.60

since it’s a discount, you subtract from the original price so:

$18 - $3.60 = $14.40
