| Question 1110078:  Suppose that a theater sells matinee tickets for $7.00, while normal tickets are $12.50, and 3D tickets are $18.00. On a certain day, 8,526 people visited the theater and twice as many people bought matinee tickets or normal tickets as those who bought 3D tickets. A total of $105,304.50 in ticket sales was collected. Determine how many of each type of ticket was sold.

On a certain day, 8,526 people visited the theater and twice as many people bought matinee tickets or normal tickets as those who bought 3D tickets. A total of $105,304.50 in ticket sales was collected. Determine how many of each type of ticket was sold. --------------------------
 Equations:
 Value Eq:: 7m + 12.5n + 18D = 105,304.50 dollars
 Quantity Eq:: m + n + D = 8526
 Quantity Eq:: m+n = 2D
 ----------------------------
 Substitute::
 2D+D = 8526
 D = 2842
 ------
 7m + 12.5n = 105,304.5-18*2842
 m + n = 8526-2842
 -----------------------
 7m + 12.5n = 54148.5
 7m + 7n = 7*5684
 ------
 5.5n = 14360.5
 n = 2611 tickets
 ----
 m = 8526-2842-2611 = 3073
