The function C that represents how much more it costs to rent a luxury car than an economic car is; C = 0.35M + 5.45
We are given the function that represents the charge E(in dollars) to rent an economy car is given by the function;
E = 0.80M + 10.95
Similarly, we are given the function that represents the charge L in dollars to rent a luxury car as;
L = 1.15M + 16.40
Now, we want to find the function C that represents how much more it costs to rent a luxury car than an economic car and this is;
C = L - E
C = 1.15M + 16.40 - (0.80M + 10.95)
C = 1.15M - 0.80M + 16.40 - 10.95
C = 0.35M + 5.45
