There were 787 general admission and 352 reserved seat tickets sold.
Step-by-step explanation:
Let g=general admissions, r=reserved seats
So, g+r=1139
So, 2.00g+3.50r=2806.00
Solving for g in the first equation
g=1139-r
Replacing the value of g in the second equation
2.00(1139-r)+3.50r = 2806.00
Distribute
2278-2.00r+3.50r = 2806.00
2278+1.50r = 2806.00
1.50r = 528
So, r = 352
Now plug in the value of r into one of the original equations
g+352=1139
So, g=787
Here 787 * 2.00 + 352 * 3.50 = 2806.00
There were 787 general admission tickets sold and 352 reserved seat tickets sold.
