Answer:
$465 is the answer.
Step-by-step explanation:

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.
[tex]15(7)+40(9)[/tex]
= [tex]105+360[/tex]
= $465
Therefore, Ben charges $465.
