Eli will photograph a wedding for a flat fee of $400 or for an hourly rate of $120. For what lengths of time would the hourly rate be less expensive?

1, 2, or 3 hours. I used this formula:
120(n)<400, where n is the number of hours.

120(1) < 400

120(2) < 400

120(3) < 400

120(4) > 400

So the hourly rate is less expensive under four hours.
