the resale value of a go-kart decreased by $20 for every hour it is used after how many hours does the value decreased by $400

Answer :

In order to find after how many hours the value will decrease by $400, we just need to divide this value by the change per hour of $20, so we have:

[tex]\frac{400}{20}=20[/tex]

So after 20 hours the value will decrease by $400.
