Two rental car companies are running specials this month. At Jenny's Rentals, customers will pay $40 to rent a mid-sized car for the first day, plus $14 for each additional day. At Middletown Rent-a-Car, the price for a mid-sized car is $50 for the first day and $4 for every additional day beyond that. At some point, renting from either one of the companies would cost a customer the same amount. How many additional days would that take? How much would the customer pay?
