Question

Keith decided to look at new and used cars. Keith found a used car for $36000, A new car is $40000, so what percent of the price of a new car will Keith pay for a used car?

Answer 1

Keith paid `90%` of the price of a new car for the used car.

Explanation:

To calculate that, we have to find what percentage of `40,000` is `36,000`. Considering the percentage as `x`, we write:

`40,000xxx/100=36,000`

`400cancel00xxx/(1cancel00)=36,000`

Divide both sides by `400`.

`400/400xx x=(36,000)/400`

`(1cancel400)/(1cancel400)xx x=(360cancel00)/(4cancel00)`

`x=360/4`

`x=90`

The answer is `90%`.
