The original cost of the skirt was $39.71.
This can be found by first calculating what the total cost of the items was originally. Since you spent $31.50 on items at 34% of their original price, the total cost can be found by dividing the new total by the percentage.
$31.50/.34 = $92.65.
Now we need to find the original price of the blouse. We repeat the same action with the $18 and the percentage.
$18/.34 = $52.94.
Now we can subtract the original cost of the blouse from the original cost of both items.
$92.65-$52.94 = $31.71.

Answer:
The original price of the skirt is $24
Step-by-step explanation:
The question must be 3/4 of their original price. So, I will solve this using 3/4 as 34 is unclear and does not suit the question.
Lets assume that the price of the blouse be = x
Lets say the price of the skirt is = y
Now, given is that 3/4 of the price together for both items is $31.5 0
This means,
[tex]\frac{3}{4}(x+y)=31.50[/tex] ..... (1)
The original price of the blouse is $18 so, x= 18 .............(2)
Putting x=18 in equation (1)
[tex]\frac{3}{4}(18+y)=31.50[/tex]
[tex]3(18+y)=31.50*4[/tex]
[tex]3y+54=126[/tex]
[tex]3y=72[/tex]
y=24
Hence, the original price of the skirt is = $24.
Check:
Original price of both items = [tex]18+24=42[/tex]
And 3/4 of 42 is [tex]\frac{3}{4}*42= 31.50[/tex]
So, the correct answer is $24.
