Answer:

$24

Step-by-step 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
