There were 144 people at the basketball game. Tickets for the game are $3.50 for students and $5 for adults. If the total money received for admission was $492.50, which of the following would model the situation:

Answer 1

I would bet it would be the one that has

x+y = 144 and 3.5x + 5y = 492.5
where x is the number of students and y is the number of adults

Answer 2

the choice which says something like
c+a = 144
3.50c + 5.00a = 492.50

Answer 3

s + a = 144 so a = (144-s)
3.50 s + 5.00 a = 492.50

3.50 s + 5.00 (144-s) = 492.50
- 1.50 s = -227.50
s = 151 2/3
2/3 of a student ?

Answer 4

I have come across many fractional students

Answer 5

what are the situations.
