To rent a certain meeting room, a college charges a reservation fee of
$41 and an additional fee of $6.60 per hour. The chemistry club wants to spend less than $87.20 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for t.
t = # of hours Make inequality: 6.6t + 41 < 87.2 Subtraction: 6.6t < 46.2 Divide: t < 7 That means that the chemistry club can use the meeting room for less than 7 hours.
