key words:
Marked at half price means the CD is 1/2 the original value
Less means minus,
So, with the half price and discount:
let x = price of original CD
(1/2)*x-4.50 = 4.50
solve for x to find the original price of the CD
need help

I do not understand
take 4.50 off half x and end up with 4.50
(1/2) x = 9
x = 18
(1/2) x = 9
x = 18
