To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $6 per hour. the chemistry club wants to spend less than $91 on renting a room. what are the possible numbers of hours the chemistry club could rent the meeting room? use t for the number of hours. write your answer as an inequality solved for t,

T= # of rental hours

Multiply number of hours rented by the cost per hour, add that total to the reservation fee. The total needs to be less than $91.

Reservation + ($ per hr * # hrs) < $91

$19 + $6t < $91
subtract 19 from both sides

6t < 72
divide both sides by 6

t < 12

ANSWER: To spend less than $91, they need to rent the room less than 12 hours.

Hope this helps! :)
