Question

Tammy will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $75 and costs an additional $0.50 per mile driven. The second plan has no initial fee but costs $0.60 per mile driven. How many miles would Tammy need to drive for the two plans to cost the same?

Answer 1

f=75+.5m,

s=.6m

For f=s

.6m=75+.5m subtract .5m from both sides

.1m=75 divide both sides by .1

m=750mi

So she would have to drive 750 miles for the two plans to cost the same.
