Ahair salon charges a fixed rate of $25.00 for a haircut and then an additional 515 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 525

you have a fixed rate of $25, meaning you get a haircut, it's $25

ANY other service is an extra $15

So, let's make the equation...

y=15x+25

Now, to just get a haircut it's $25.

But, let's say you get a haircut+shampoo

It'd be..

y=15(1)+25

y=$40

Another one..

You get a haircut+shampoo+highlight

y=15(3)+25

y=$70
