You can put this solution on YOUR website! 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
.
Let x = number of services
then
f(x) = 15x + 25 (this is your function)
.
how many services you had if you were charged $115?
set f(x) to 115 and solve for x:
f(x) = 15x + 25
115 = 15x + 25
90 = 15x
6 = x
