I have this tough HW problem...can someone please give me a hint on how to solve it?? Here it is:
Tickets for a play cost $6 each for adults and $3 each for children. If
160 of these tickets were bought for a total of $816, how many adult tickets
were bought?
Thanks in advance.

Woohoo! Math!
I love math.
Jassi, what you would do is set up two equations:
Let A be the number of adult tickets and let C be the number of child tickets.
Based on the info you gave,
A + C = 160
and
6A + 3C = $816
Take the top equation and isolate the variable C, and you get
C = 160 - A
Plug that equation into the second equation
(6A + 3C = 816), so you get
6A + 3(160 - A) = 816
From there, solve for A. I got 112.
Hope this helps!
