Question

To rent a certain meeting room, a college charges a reservation fee $18 and an additional fee of five dollars per hour. The chemistry club want to spend less and $78 on renting the room what are the possible numbers of hours in the chemistry club convention for the meeting room

Answer 1

This problem would be best modeled by an inequality.

Let t = the number of hours.

18 + 5t < 78

5t < 60

t < 12

The way the question sounds, it would not be a lessthan or equal to, because they want to spend less than 78. It would be a less than or equal problem if they said "no more than 78"
