a hair salon charges a fixed rate of $25.00 for a haircut and then an additional $15 for any service . write a function to model the cost of services there and then determine how many services tou had iy you werecharged $25


A. F(x)= 15x+25; f(0)= 25
B.)f(x) = 25x+15;f(.4) =25
C.) f(x) = 15 x +25; f(25) =400
D.) f(x) = 25x +15;f(25) =640
