Question

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

$36
and an additional fee of
$8.80
per hour. The chemistry club wants to spend less than
$115.20
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
.

Answer 1

So this is an algebra question, where you have have to setup the equation. Let t represent the number of hours.
36 + 8.80t < 115.20 we can then setup the equation like this to solve for the max hours.
36 + 8.80t= 115.20

Now solve
8.80t = 115.2-36
8.80t= 79.2
t = 9

so t < 9
