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

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