Dan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of 53.96
and costs an additional 0.17
per mile driven. The second plan has an initial fee of 57.96
and costs an additional 0.12
per mile driven. How many miles would Dan need to drive for the two plans to cost the same?

Respuesta :

53.96+0.17x =57.96+0.12x
0.17x-0.12x=57.96-53.96
0.05x=4.00
x=80 mi
