Trey will rent a car for the weekend.

Question

Trey will rent a car for the weekend. He can choose one of two plans. The first plan has no initial fee but costs $0.90

 per mile driven. The second plan has an initial fee of $70

 and costs an additional $0.70

 per mile driven. How many miles would Trey need to drive for the two plans to cost the same?

Answer 1

70+.7m=.9m

.2m=70

m=70/.2=350 miles

.9(350)=$315

=70+.7(350)=$315
