Word Problem Algebra 2?

A plumber charges a flat fee and a fee per hour foe his jobs. For a 3 hour job he charges $125 for a 6 hour job he charges $200. What would he charge for an 8 hour job?

I'm trying to figure out the correct algebraic way to solve this.

Let f = flat fee and h = hourly fee

f + 3h = 125

f + 6h = 200

3h = 75

h = 25

f + 75 = 125

f = 50

f + 8h = 50 + 8(25) = 50 + 200 = 250

He would charge $250 for an 8-hr job.
