Question

To rent a certain meeting room, a college charges a reservation fee of $49

 and an additional fee of $8.90

 per hour. The math club wants to spend less than $129.10

 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

.

Answer 1

This is a linear function.

8.9t+49 < 129.10

8.9t < 80.1

t < 80.1/8.9

t < 9 hours

Answer 2

49 + 8.90t < 129.10

t < 80.10/8.90 = 9 hours

they can rent for less than 9 hours
