Question

rachel paid $492 for a camera during a 25% off sale. what was the camera's regular price?

Answer 1

Since she paid $492 when the item was 25% off, she paid 75% of the original price. You can set up the following equation to solve for the original price.

492 = 0.75 (aka 75%)
492/0.75 = 0.75/0.75
656 = 1 (aka 100%) = original price

Check:
656(0.25) = 164
656 - 164 = 492

The original price of the camera was $656!
