A movie theater has a seating capacity of 233. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults. There are half as many adults as there are children. If the total ticket sales was $ 1692, How many children, students, and adults attended? I kinda need to know these answers asap. I have tried everything to try and solve it but nothing worked. Please help.
