To determine the hourly rate that the cleaning service charges, Phillipe should first account for the flat fee for supplies. Here's the correct approach:

1. Subtract the supply fee of $15 from the total cost of $232 to find the cost attributed to the hourly rate.
2. Then, divide that difference by the number of hours, which is 3.5.

So the correct response is:

Subtract the supply fee, $15, from the total cost, $232. Then, divide the difference by the number of hours, 3.5.
