Question

to rent a certain meeting room a college charges a reservation fee of $35 and a additional fee of $7.80 per hour . The chemistry club wants to spend $74.00 on renting the meeting room. what are the possible amounts of time for which they could rent the meeting room

Answer 1

5 hours

Explanation:

The equation to solve this is 7.80h+35=74.

7.80 represents the cost per hour, h represents the number of hours, 35 is the reservation fee, and 74 represents the total money.

7.80h+35-35=74-35

7.80h=39

h=5
