Answer:80

Step-by-step explanation:x is the original price.

x - .25*x is the sale price.

the sale price is 60.00

x - .25*x = 60

x - .25*x is equal to .75*x

.75*x = 60

divide both sides of this equation by .75 and you get:

x = 60/.75 = 80

the original price was 80

25% of 80 = 20

80 - 20 = 60

number look good.

solution is that the original price was 80 dollars.
