F(x) =
What is the answer

Answer 1

`F(x)=25x+50`

Explanation:

First, we know that for every hour for labor he charges $25

So, let x = # of hours

Thus, 25x

Second, he charges $50 for a house call. This does not depend on the # of hours, and serves as our "Starting Pay"

So, we combine and get F(x)=25x+50, where F(x) is the amount he charges
