Answer:
295 general admission tickets and 388 upper reserved tickets were purchased.
Explanation:
Let the number of general admission tickets be = x
Let the number of upper reserved tickets be = y
In total there were 683 tickets sold.
So, we get
........(1)
The general admission tickets cost $6.50 and the upper reserved tickets cost $8.00 and total amount of money spent was $5021.50.
So, we have another equation:
......(2)
Multiplying (1) by 8 and subtracting (2) from (1), we get;

x = 295
And

So,


y = 388
So, 295 general admission tickets and 388 upper reserved tickets were purchased.
