A hair salon charges a fixed rate of $25.00 for a haircut and then an additional $15 for any other services. Write a function to model the cost of services there and then determine how many services you had if you were charged $115.

• f(x) = 15x + 25; f(6) = 115
• f(x) = 25x + 15; f(6) = 165
• f(x) = 15x + 25; f(115) = 1750
• f(x) = 25x + 15; f(115) = 2890
