Part 1: Linear Equation
Variables:
- Let \( S \) = number of standard tickets sold
- Let \( P \) = number of premium tickets sold
Equation: Since each standard ticket allows 1 attendee and each premium ticket allows 2 attendees, the total number of attendees can be represented by the equation:
\[ S + 2P = 300 \]
This equation means that the total number of attendees from standard and premium tickets combined must equal the 300 seats in the theater.
Part 2: Ticket Sales Scenario
Given:
- Standard tickets sold \( S = 100 \)
- Premium tickets sold \( P = 100 \)
Calculate total attendees:
Using the equation from Part 1:
\[ 100 + 2(100) = 100 + 200 = 300 \]
Conclusion: The total number of attendees is 300, which exactly fills the theater. Therefore, the theater is filled with this ticket sales decision.
