A theater has a seating capacity of 600 and charges $6 for children, $11 for students, and $16 for adults. At a certain screening with full attendance, there were half as many adult as children and students combined. The receipts totaled $1,800. How many children attended the show?
Let x be the number of tickets sold to children, y be the number of tickets sold to students, and z be the number of
tickets sold to adults.
