Answer
$328$ adult tickets, or (C)
Work Step by Step
We're solving for the number of adult tickets, so let that be $x$.
In this case, student tickets would be $x+62$.
If there were $4$ times as many adults as child tickets, child tickets would be $0.25x$
We know the total number of tickets is $800$:
$x + 0.25x + (x + 62) = 800$
Solve for $x$:
$2.25x+62 = 800, 2.25x = 738, x = 328$
