Question

Jade buys a blouse and a skirt for 3/4 (fraction) of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt? Enter your answer in the box.

Answer 1

$24

Explanation:

Original price of blouse = $18

Discounted price of blouse = 3/4 x 18 = $13.50

Discounted blouse + discounted skirt = $31.50

⇒ 13.50 + discounted skirt = 31.50

⇒ discounted skirt = 31.50 - 13.50 = 18

Let S be the original price of the skirt.

If the discounted skirt is 3/4 of it's original price, then

$18 = (3/4) S

S = 18 ÷ 3/4 = 24

Therefore, the original price of the skirt is $24
