Mr. Peterson traveled to Los Angeles on business. He was interested in renting a car for one day to travel from the airport to a client’s office. ZoneThree Car Rental quoted him a rental cost of $40 per day plus an additional 8 cents per mile driven. ZoneFour Car Rental provided a quote for $35 per day in rental costs plus 12 cents per mile driven. How many miles would Mr. Peterson need to drive in order for the cost of both rental companies to be equal?
