Answer:

$465 is the answer.

Explanation:

The equation is given as :


15h+40f

Where h is the number of hours worked and f is the number of fixtures installed.

We have been asked how much does Ben frank charge when he works 7 hours and installs 9 fixtures?

So, we will put the values of h 7 and f = 9 in the equation.


15(7)+40(9)

=
105+360

= $465

Therefore, Ben charges $465.
