You can put this solution on YOUR website! decreased to $0.54 per mile in 2009.
a) find a linear equation that relates the average cost C of operating a standard-sized car and the number X of miles it is driven.
C(x) = 0.54x
-------------------------
b)what is the annual cost if you drive 15,000 miles?
C(15000) = 0.54*15000 = $8,100
