S + a = 300...s = 300 - a
8s + 12a = 3200
8(300 - a) + 12a = 3200
2400 - 8a + 12a = 3200
-8a + 12a = 3200 - 2400
4a = 800
a = 800/4
a = 200 <==== 200 adult tickets
s = 300 - a
s = 300 - 200
s = 100 <=== 100 student tickets
We have by distributivity of limits over sums, and continuity of
and
, that

Given
, it follows that

Irrational
the number is endless in its digits (much like pi) and thus is irrational
