Question

Marked at half price and less the dealer discount of $4.50, the CD cost $4.50. How much was the original price of the CD?

Answer 1

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

Answer 2

I do not understand

Answer 3

take 4.50 off half x and end up with 4.50
(1/2) x = 9
x = 18
