Answer:
The possible numbers the chemistry club could rent the room is less than 6 hours(t<6)
Step-by-step explanation:
Reservation fee = 15
Additional fee of 5 per hour
If the chemistry club wants to spend less than 45 on renting the room, let the possible number of hours be t.
t = time
15 + 5t < 45
5t < 45 - 15
5t < 30
t < 30/5
t < 6 hours
