Hello Roka,
So to answer this question, you have to know what parts are variable and what parts are fixed. And since it looks like a multiple choice question, I'll answer it as fully as possible and you can use it to make your selection.
Initial fees are typically fixed. So in this case it's $75.
Hourly fees are variable. So for that, you use the rate, $65 per hour in this case, and multiply it by the time.
In a situation like this your equation would look like:
Cost = ($65 x h) + $75
I'm using "h" to represent the number of hours. Since you're given 6 hours, you just plug 6 in for "h" and solve.
I'll let you finish the remaining answer on your own. As a hint, the answer will fall between $400 and $500.
Hope this helps! If you need added assistance, I'm available to tutor through video conference. Good luck!
