The cost for x number of students to attend an after school sporting event can be represented bu the functon c(x). if c(124) = 558, select the following statements that are true.

1. 124 students paid to attend the event.

2. 558 students paid to attend the event.

3. the cost for one student to attend the event cannot be determined.

4. the cost for one student to attend the event is $4.50

5. the event generated $124 from student revenue.

Alright! Given that C(x) is Cost(Students) = 558, we can eliminate:

2. 558 students paid to attend the event.
5. The event generated $124 from student revenue.

Now, in order to find the cost per student we simply divide 124 on both sides:



124 cancels on the left and 558/124 is 4.5 or $4.50. 

Since we just determined the cost of one student, we can eliminate 3.

To check if 124 students paid, we simply add the cost to the equation and check:

4.5(124) = 558

558 = 558 √

It checks out, so we determined that both 1 and 4 are correct.
