Answer:
A chaperone ticket costs $13.
Explanation:
Let a student ticket cost x.
Then a chaperone ticket costs x + 5.
The tickets for 40 students cost 40x.
The tickets for 4 chaperones cost 4(x + 5).
The total cost equals $372.
40x + 4(x + 5) = 372
40x + 4x + 20 = 372
44x = 352
x = 352/44
x = 8
A student ticket costs $8.
A chaperone ticket costs x + 5 = 8 + 5 = 13.
A chaperone ticket costs $13.
