Question

To rent a certain meeting room, a college charges a reservation fee of 15 and an additional fee of 5 per hour. The chemistry club wants to spend less than 45 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?

Answer 1

The possible numbers the chemistry club could rent the room is less than 6 hours(t<6)

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
