Answer:
a = 350 s = 402
Explanation:
s + a = 752 where s is the number of student tickets and a = adult tickets
s = a + 52 since there were 52 more student tickets than adult tickets sold
so substitute for s: (a + 52) + a = 752, so 2a = 700 so a = 350
If adult tickets were 350 then the student tickets are 402
