The audience of a movie theatre is 400 people consisting of adults, teens, and children. The ticket prices are $40 for adults, $20 for teens, and $10 for children. The total amount of money taken in is $10600. The number of children tickets sold is 200 less than the number of adult and teens tickets in total. Use Cramer’s rule to calculate the number of adults, teens and children that are in attendance. Include the following steps: A. Define each variable. B. Write each equation. C. Rewrite as systems in matrix form with the coefficient, variables, and constants matrices.
