Full Price: $60
1st teacher: Pays 1/3 of final cost : $20
2nd teacher: Pays 1/4 of final cost : $15
3rd teacher: Pays 1/5 of the final cost: $12
4th teacher: Pays the remainder: $13

The method:
To find out how much each one paid, the same method is used for all. The relative percentage they paid is given, for e.g. the first teacher paid 1/2 the sum of money the other teachers paid so this means that if the other teachers paid $50, she paid $25, $25 + $50 =$75, 25/75 = 33% Therefore she paid 1/3 of the final cost being $20
