Denise would have to take seven hours to charge the same amount of money as tiana. furthermore, it would cost the same amount as that is what the prompt is asking for.

to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.

after subtracting i got $273

from there i divided $273 by $39 and got 7 (the amount of hours it would take)
