Use t for the numbers of hours

Question

To rent a certain meeting room, a college charges a reservation fee of $14 and an additional fee of $5 per hour. The chemistry club wants to spend at most $44 on renting the room . What are the possible numbers of hours the chemistry club could rent the meeting room?

Answer 1

If H = number of hours to rent, then the Cost = 14 + 5H

You want this to be less than or equal to 44, So, 14 + 5H <= 44

Then 5H <= 44-14 = 30 or H <= 30/5 = 6 hours
