Answer:
20%
Step-by-step explanation:
We know:
397 total
53 fewer student tickets than adult tickets
Variables: A for adult tickets, S for student tickets
Known Equations:
a + s = 397
a = s + 53
Solving:
2s + 53 = 397 so 2s = 344 so s = 172
s + a = 397
172 + (172 + 53) = 397 so 172 + 225 = 397
Adult tickets sold: 225
Student tickets sold: 172
