Question

Raphael paid $632 for a camera during a 20% off sale. What was the camera's regular price?

Answer 1

The camera's regular price was `$790`.

Explanation:

We can express discount amount as `x` and the original price of the camera as `x+632`. The equation to determine the price will be:

`(x+632)xx20/100=x`

Simplify.

`(x+632)xx(1cancel(20))/(5cancel(100))=x`

Multiply both sides by `5`.

`x+632=5x`

Subtract `x` from both sides.

`632=4x`

Divide both sides by `4`.

`158=x`

Since the discount amount `(x)` is `158`, the original price `(x+632)` will be `(158+632)=790`.
