how to write this as an equation?
A phone company charges 26.95 a month with .24 cents per minute. but you get a 100 free minute
That doesn't include the first 100 minutes free in the equation though, I know 26.95 + .24x but i need another piece.

You would pay $26.95 for the first 100 minutes
After 100 minutes:
Let x = minutes
Total = .24(every minute after 100) + monthly charge
y = .24(x - 100) + 26.95
The (x - 100) would give you the number of minutes you will be charged for
Example; if you call 137 minutes, you are charged for 137 - 100 or 37 minutes because the 1st 100 minutes are free
So the equation is
y = .24(x - 100) + 26.95 for every minute over 100
