Question

An LCD TV is on sale for 24% off. If the original price was $800, find the sales price.

Answer 1

The sales price is $608.

Explanation:

Being on sale for 24% off means that the sales price is 100-24 = 76% of the original price.

This can be solved by a rule of three.

The original price is 800

So

$800 - 1

$x - 0.76

`x = 0.76*800 = 608`

The sales price is $608.

Answer 2

24% = 0.24

multiply that by the price:

800 * 0.24 = 192 ( discount)

800-192 = $608 sale price
