Question

To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $4 per hour. The chemistry club wants to spend at most $47 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?

Answer 1

7 hours

Explanation:

There is $47 total dollars. The reservation fee is $19 dollars. Subtract the two:

47-19= 28 dollars

Now the per hour fee is 4 dollars an hour. And you have 28 hours. So divide the two to get maximum hours:

28/4=7 hours

Answer 2

The possible number of hours the chemistry club can rent the meeting room is 7 hours.

Explanation:

h=hours

19+4h=47

Subtract 19 from both sides of the equation.

4h=28

Divide 4 from both sides of the equation.

h=7

The possible number of hours the chemistry club can rent the meeting room is 7 hours.

Hope this helps :)
