Equation for tickets sold: Equation for money made:
x+y=1787 4x+3y=5792
Solve for x using substitution:
x=1787-y
Plug it into the other equation to find the value of y:
4(1787-y)+3y=5792
7148-4y+3y=5792
-y=-1356
y=1356
Now plug y back into any equation:
x+1356=1787
x=431
1356 general admission tickets were sold, and 431 reserved seats were sold.
x+y=1787 4x+3y=5792
Solve for x using substitution:
x=1787-y

4(1787-y)+3y=5792
7148-4y+3y=5792
-y=-1356
y=1356
Now plug y back into any equation:
x+1356=1787
x=431
1356 general admission tickets were sold, and 431 reserved seats were sold.
There were 431 reserve seat tickets and 1356 general admission tickets sold.
What is Cost Function?
A cost function is a mathematical formula used to used to chart how production expenses will change at different output levels. In other words, it estimates the total cost of production given a specific quantity produced.
Let 'x' represent the number of reserve seats that were sold,
then '1787-x' represents the number of general admission tickets sold
we then have the following cost equation:
5792 = 4x + 3(1787-x)
solving for 'x' we have:
x = 431
1787-431 = 1356
Thus, there were 431 reserve seat tickets and 1356 general admission tickets sold.
