Raphael paid $656 for a camera during a 20% off sale. What was the camera's regular price? Please work the problem and show your work so I can understand it better.

Respuesta :

The answer is $820.
I found this by 0.8x = 656
(Remember, a 20% discount means that it costs 80%, or 0.8, of the original price)
Then, divide 0.8 on both sides:
0.8x/0.8 = 656/0.8
This leaves you with:
x = 820
