Just needed some help on this problem.
Write the Function C(x) which is the annual cost of fuel for your vehicle as a function of the miles per gallon X. (Do not use a specific number for miles per gallon for X here)
cost of fuel = 3.98
car gets 27.5 on average.
So far all I can think of is C(x) = 3.98x then I'm lost. Any help would be appreciated. Thanks.
