-----
CW = 20.25d + 0.14m
ER = 18.25d + 0.22m
----
Cost for a 3 day trip:
CW: 20.25*3+ 0.14m = 60.75 + 0.14m
ER: 18.25*3+ 0.22m = 54.75 + 0.22m
-------------------------------------------
San plans to do a lot of driving on his 3-day trip. Which company should Sam go with? Explain your choice.
Go with CW as their milage rate is 8 cents lower than ER's.

Does the difference in cost go up or down as mileage increases? Support your answer.
The difference decreases till the 8 cent per mile difference
is greater than the $6.00 fixed cost difference for CW
