Reservation fee of 47.00 and additional fee of 7.40 per hour. Spend less than 91.40. Possible about if time for room
KIM [24]

Answer:

The room can be rented for 6 hours with $91.4

Step-by-step explanation:

If my guess was correct, there was a reservation fee of $47, and there was another fee of $7.4 per hour and the question is asking for how many hours can be rented with $91.4 and the variable t to represent the time.

First, $91.4-$47 as that is the reservation fee. $91.4-$47 = $44.4

Next, we figure out how many hours can we rent with $44.4. Since one hour of rental costs $7.4, t = 44.4/7.4

Finally, we just divide. This is a relatively simple question when thinking about how straightforward this is.

44.4/7.4 = 6

Recheck:

7.4*6 = 44.4

t = 6
