Answer: f(x) = 400 + 25x

Explanation:

When writing this equation we want to separate constants from dependent variables.

We know that Denzel will always charge $400 for a flat charge, which makes that our constant. It is then claimed that he will be paid $25 an hour, which will be dependent of the function's x-value, representing hours.

We therefore end up with f(x) = 400 + 25x
