Suppose that a car rental agency gave you the following choices.

Option A: $30 per day plus 40 cents per mile.

Option B: flat $50 per day

(a) Write equations for cost per day c for options A and B. (Use m for distance in miles)

(b) Graph the equations for options A and B

c= $30.00 plus 40 cents = 30. + .04= 34.00 (option A)

c= $50.00 (option B)

(c) Estimate the mileage for which both rates are the same. m = 20 miles?

Would this be graphed as: 34 and 50?

- Mileage/graph -
**Steve**, Monday, January 23, 2012 at 11:56pmYou want 30+.4m=50

.4m = 20

m = 50

SO, if you drive 50 miles, A and B cost the same.
