15
Step-by-step explanation:
A ratio is comparison between two number such as
I have three dogs and two cats the ratio of cats to dogs is 2:3 or what is the ratio of cats to total pets which is 2;5
T= # of rental hours
Reservation Fee= $31
Per Hour Fee= $7.40
Multiply number of hours rented by the cost per hour, add that total to the reservation fee. The total needs to be less than $97.60.
Res Fee + ($ per hr * # hrs) < $97.60
$31 + $7.40t < $97.60
subtract 31 from both sides
7.40t < 66.60
divide both sides by 7.40
t < 9
ANSWER: To spend less than $97.60, they need to rent the room less than 9 hours.
