How much will the ticket cost How many rooms will they need to reserve? How do you know?
How much will it cost for everyone to stay one night at the hotel?

For all students combined it will be 4,144 because 112x37 = 4,144$

For adults it will be 13x55= 750 $

They will need to reserve about 10 rooms because 112+37 divided by 12= 10 and 10•80=800 so 800$ for 1 night for everyone !
I hoped this helps

$7.50x+$4.50y=midk it's been awhile since i've done one of these
