+577 the junior class is renting a laser tag facility with a capacity of 325 people. the cost for the facility is $1200. the party must have at least 13 adult chaperones
a. if every student who attends shares the facility cost equally, what function models the cost per student C with respect to the number of students N who attend? what is the domain of the function? how many students must attend to make the cost per student no more than $7.50?
b. the class wants to promote the event by giving away 30 spots to students in a drawing. how does the model change? now how many paying students must attend so the cost for each is no more than $7.50?
someone explain how to solve this it confuses me beyond comprehension

a. if every student who attends shares the facility cost equally, what function models the cost per student C with respect to the number of students N who attend?
Cost per student = $1200/N
what is the domain of the function?
domain:1≤N≤(312−additionaladultchaperones)N∈Z
how many students must attend to make the cost per student no more than $7.50?
1200N≤7.5012007.5≤NN≥12007.5N≥160
b. the class wants to promote the event by giving away 30 spots to students in a drawing. how does the model change? now how many paying students must attend so the cost for each is no more than $7.50?
It doesn't change the number of PAYING students who must attend. It will still need to be 160 or more paying students.
BUT N is not paying students, it is all students so the model does change.
Cost per attending student that is actually paying will be
Costperpayingstudent=1200N−30
+577 thank you so much! i have been stuck on this question for a few hours now.
