Question

Amy will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.60

 per mile driven. The second plan has an initial fee of $50

 and costs an additional $0.40

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

Answer 1

.6m = 50 +.4m

.2m = 50

m = 50/.2 = 500/2 = 250 miles for both plans to cost the same

.6(250) = $150 = 50+.4(250) = 50+100 = $150
