topjm [15]

Answer:

$257$ adult tickets

Step-by-step explanation:

Let x be the total sold adult ticket.

Given:

Total 582 tickets were sold.

There were 68 fewer student tickets sold than adult tickets

Then there were $x-68$ students.

So, The total sold ticket equation is

$x+(x-68)=582$

$2x-68=582$

$2x=582-68$

$x=\frac{514}{2}$

$x=257$

Therefore, 257 adult tickets were sold
