Step-by-step explanation:

Key skills needed: Proportions, Variations, Equations

1) Each student ticket costs $12.50.

2) this means for every 1 ticket purchased (s), $12.50 is being added to the total cost.  

This means that The total cost is always 12.5 times the number of tickets sold.

3) This means we can make this --->  t = 12.5s
