Answer:
$465
Step-by-step explanation:
The problem statement tells you h represents the number of hours, and the number of hours is 7.
It also tells you f represents the number of fixtures, and the number of fixtures is 9.
And, the problem statement tells you the charge is 15h+40f, which is 15 times the number of hours plus 40 times the number of fixtures. Then the charges are ...
15·7 +40·9 = 105 +360 = 465
