Iola has $75. she buys a pair of shoes on sale for one-half off and a pair of socks for $6. she has $32 left. which equation can be used to find x, the regular price of the shoes?

a. x + 6 + 32 = 75
b. x + 6 = 32
c. 1/2x +6+ 32 =75
d. 1/2x +32 =75

To solve for the problem above, let x be the regular price of the shoe.
1/2x is the one-half price of the shoe then we add 6 for the pair of socks,
1/2x + 6, then lola has 32 left so we add that too, 1/2x + 6 + 32 = 75. The total amount of lola spent is 75 - 32, which is 1/2x + 6.

I’m having a hard time understanding your question
