Problema Solution
Tony will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $75 and costs an additional $0.40 per mile driven. The second plan has no initial fee but costs $0.60 per mile driven. How many miles would Tony need to drive for the two plans to cost the same?
Answer provided by our tutors
Let 'x' be the number of miles that tony passed
First Plan: initial fee of $75 and costs an additional $0.40 per mile driven thus the total money spent will be
75 + 0.40x
Second Plan: no initial fee but costs $0.60 per mile driven thus the total money spent will be
0.60x
we want the two plans to cost the same
75 + 0.40x = 0.60x
by solving the equations we find
x = 75/(0.60 - 0.40)
x = 375 miles
Tony needs to drive 375 miles for the two plans to cost the same.
