Raphael paid 636 for camera during a 60% off sale with the cameras regular price

60% off means u paid 40%

40% of the regular price = 636

0.40x = 636

x = 636/0.40

x = 1590 <==

Your question needs some rewording. How does this sound? " Raphael paid $636 for camera during a 60% off sale. The camera's regular price is x. Find this price."

If the price is 60% lower than usual, Raphael is paying only (100% - 60%), or 40%, for the camera.

Thus, 0.40x = $636. Divide both sides of this eq'n by 0.40 to find the original price of the camera.

x = $636/0.40 = ?
