Answer:
The sales price of the skirt was $14.3.
Step-by-step explanation:
From the information given, you know that the total for the three items is $32.35 which is:
x+y+z=32.35
x is a skirt
y is a pair of shoes
z is a pair of socks
Also, you know that the pair of socks costs $3.75, so you can replace the value of z and subtract this from the total amount to have the price of the skirt plus the pair of shoes:
x+y+3.75=32.35
x+y=32.35-3.75
x+y=28.6
Now, as the original prices of the skirt and shoes were the same and you know that the sum of the two items is equal to $28.6, you can divide this by 2:
$28.6/2=$14.3
According to this, the answer is that the sales price of the skirt was $14.3.
