Question

To rent a certain meeting room, a college charges a reservation fee of $37 and an additional fee of $6.70 per hour. the chemistry club wants to spend less than $97.30 on renting the meeting room. what are the possible amounts of time for which they could rent the meeting room

Answer 1

----------------------------------------------------
Define x:
----------------------------------------------------
Let the number of hours be x.

----------------------------------------------------
Construct inequality:
----------------------------------------------------
37 + 6.7x < 97.30

----------------------------------------------------
Solve x:
----------------------------------------------------
37 + 6.7x < 97.30

----------------------------------------------------
Take away 37 from both sides:
----------------------------------------------------
6.7x < 60.30

----------------------------------------------------
Divide by 6.7 through:
----------------------------------------------------
x < 9 hours

If the club wants to spend less than $97.30, they need to rent the place for less than 9 hours. A possible amount of time will be 8 hours.
