To find the answer,we can solve this by settin up an equation.
Let x be the number of adult tickets sold.
The number of students ticket sold would be:
x-74
We can then sum them up to set an equation:
x+x-74 = 676
2x = 676 + 74
x = 375
Therefore the adult tickets sold were 375.

The expression for the area of the shaded region is s^2 - pir^2
<h3>Area of composite figure</h3>
The formula for calculating the area of the shaded part in the given equation is expressed as:
Area area of square. - area of circle
Since
Area of square = s^2
Area of circle = pir^2
substitute
Area of shaded part = s^2 - pir^2
Hence the expression for the area of the shaded region is s^2 - pir^2
