Question 904241: Duke’s Car Rental rents cars at $40 plus 15 cents a mile. Mickey’s Rentals rents cars at $50 plus 10 cents a mile.
a) Write a linear equation for the cost, C, of each car rental as a function of miles, m, driven.
b) Graph both functions together. Label functions and axis and use appropriate scaling.
c) Interpret what the vertical intercept of each function represents?
d) At what miles do the rentals cost the same? What is the cost at that mileage?
e) Analyze and interpret each rental. When is each rental car the best deal?

c=.15m+40
c=.10m+50
The vertical intercept indicates the daily fee of $40 or $50
d) .15m+40=.10m+50
.05m=10
5m=1000
m=200
They are the same at 200 miles
e) the second $50 a day is better if you are going more than 200 miles a day
