Answer 1

I attached a screenshot with the correct ratio of the question.

Answer:
original price of blouse = $24

Step-by-step explanation:
Assume that the original price of the skirt is x and that the original price of the blouse is y.

We know that:
1- 3/4 of their price together is $31.5
This means that:
3/4 (x+y) = 31.5 ............> equation I

2- original price of blouse is $18.
This means that:
x = 18 .............> II

Substitute with II in I and solve for y to get the original price of the blouse as follows:
3/4 (x+y) = 31.5
3/4 (18+y) = 31.5
3 (18+y) = 31.5 * 4
3 (18+y) = 126
18 + y = 126 / 3
18 + y = 42
y = 42 - 18
y $24

Hope this helps :)
