Question

Jenny wants to rent a truck for one day. She contacted two companies. Laguana's Truck Rentals charges $20 plus $2 per mile. Salvatori's truck rentals charges $3 per mile. After how many miles will the total cost for both companies be the same?

Answer 1

20 miles.

Explanation:

Let m be number of miles.

Laguana's Truck Rentals charges $20 plus $2 per mile.

Total cost of Laguana's Truck =
`20+2m` .... (1)

Salvatori's truck rentals charges $3 per mile.

Total cost of Salvatori's truck =
`3m` ... (2)

We need to find the number of hours after that the total cost for both companies will be the same.

`3m=20+2m`

`3m-2m=20`

`m=20`

Therefore, after 20 miles the total cost for both companies will be the same.
