Two rental car companies are running specials this month. At Kevin's Rentals, customers will pay $42 to rent a mid-sized car for the first day, plus $11 for each additional day. At Hillsdale Rent-a-Car, the price for a mid-sized car is $46 for the first day and $7 for every additional day beyond that. At some point, renting from either one of the companies would cost a customer the same amount. How much would the customer pay? How many additional days would that take?
