Question

A store advertises a `20​%` discount on a `​$831` computer system.What will the sale price be?

Answer 1

`$664.80` will be the sale price.

Explanation:

There are two approaches:

• Calculate how much the discount will be and subtract it.

How much is `20%` of `$831?`

`20/100 xx 831 = $166.20`

Subtract this amount to find the sale price:

`$831 - $166.20 = $664.80`

• If `20%` is taken off the price, the sale price will be `80%`

Find `80%` of the original price.

`80/100 xx $831 = $664.80`
