Hi there! The answer is $465

The total cost can be found using the formula

15h + 40f

To find the amount of money Ben Frank charges, we need to plug in the data from the question.

h = number of hours worked = 7
f = number of fixtures installed = 9


15 * 7 + 40 * 9 = 105 + 360 = 465
Therefore, Ben Frank charges $465

~ Hope this helps you!
