Alan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $55 and costs an addi
tional $0.50 per mile driven. The second plan has no initial fee but costs $0.70 per mile driven. How many miles would Alan need to drive for the two plans to cost the same?
