a car can be rented from Johny's Car Rental for $2000 per day with no charge for mileage or from Car Rental Exclusive for $1000 per day plus $20 for each kilometer driven. If a car is to be rented from Car Rental Exclusive, for how many kilometers of intended travel does it cost less to rent from Johny's Car Rental?

Johnny’s Car Rental = $2000 Per Day

Car Rental Exclusive = $1000 + $20k (k is for kilometers)

The inequality set up would be: $2000 < $1000 + $20k

You then want to solve for k.

$2000 < $1000 + $20k

-$1000 < -$1000

$1000 < $20k

$1000/$20 < $20k/$20

50 < k or another way to write it is k > 50.

So where the number of kilometers is Greater than 50, Johnny’s Car Rental would be cheaper.
