Raphael paid $480 for a camera during a 25% off sale. What was the camera's regular price? Please work the problem and show your work so I can understand it better.
$480 is the price after the discount was added. We can then assume that $480 is 3/4 the price of the original item. To find 1/4, we simply divide by 3, which equals $160. since $160 is one quarter of the price, the original price was $640.
