If t = # of hours and F = total fee, then

F = 90 + 80t

how did I get 80? well if they get $20 for every 15 minutes, then they get 4*20 = 80 dollars for every 4*15 = 60 minutes or every hour. So they basically get paid $80 per hour and this is added to the base fee of $90

So again, the final answer is either F = 90 + 80t or F = 80t + 90 where t = # of hours and F = total fee
