Math Problem Statement
Formulate a system of equations for the situation below and solve.
For the opening night at the Opera House, a total of 1000 tickets were sold. Front orchestra seats cost $80 apiece, rear orchestra seats cost $60 apiece, and front balcony seats cost $50 apiece. The combined number of tickets sold for the front orchestra and rear orchestra exceeded twice the number of front balcony tickets sold by 400. The total receipts for the performance were $63,600. Determine how many tickets of each type were sold.
Solution
To solve this problem, let's define the variables for the number of tickets sold for each section:
- Let represent the number of front orchestra seats sold.
- Let represent the number of rear orchestra seats sold.
- Let represent the number of front balcony seats sold.
Now, based on the information provided in the problem, we can formulate the following system of equations:
Equation 1: Total number of tickets sold
The total number of tickets sold is 1000, so:
Equation 2: Relationship between front orchestra, rear orchestra, and front balcony tickets
The combined number of front and rear orchestra tickets exceeds twice the number of front balcony tickets by 400. This gives:
Equation 3: Total receipts
The total receipts for the performance were $63,600. Each ticket price for the different sections is provided, so:
System of equations:
Now, let's solve this system step by step.
Step 1: Solve for using equation (2)
From equation (2): We'll substitute this expression for into equations (1) and (3).
Step 2: Substitute into equation (1)
Substitute into equation (1): Simplify: So, 200 front balcony tickets were sold.
Step 3: Substitute into equation (2)
Substitute into equation (2): So, .
Step 4: Substitute and into equation (3)
Substitute into equation (3): Simplify:
Step 5: Solve the system of two equations
We now have the system:
Solve the first equation for :
Substitute into the second equation: Simplify: So, 280 front orchestra tickets were sold.
Step 6: Solve for
Substitute into : So, 520 rear orchestra tickets were sold.
Final Answer:
- Front orchestra tickets sold:
- Rear orchestra tickets sold:
- Front balcony tickets sold:
