You can put this solution on YOUR website!
sale price = 480.
this was discount of 20% off the original price.
let x = original price.
x - .20 * x = 480
simplify to get .80 * x = 480
solve for x to get x = 480 / .8 = 600.
original price was 600.
20% off = 120.
sale price is 600 - 120 = 480.
solution looks good.
solution is original price was 600.
