First, step.... what type of tickets are being sold ?
OpenStudy (anonymous):
adult and children
OpenStudy (phi):
yes. The question asks "how many tickets have to be sold"
So we are interested in the *number of adult* and *number of children* tickets.
2nd step: give "number of adult tickets" a "name" : call it A
same for # of children tickets: call the number C
OpenStudy (phi):
if you sold A tickets and C tickets, the total is A+C
what is the most A+C can be ?

You do know it is a bad idea to sell more tickets than you have seats for, right ?
OpenStudy (anonymous):
Yes and we only have 240 seats
OpenStudy (anonymous):
so A + C < = 240
OpenStudy (anonymous):
and 8a + 4c <= $1000
OpenStudy (mertsj):
This one?

yes this one
OpenStudy (mertsj):
What is the matter with the answers you have already been given?
OpenStudy (anonymous):
I got 2 equations
a + c < = 240
8a + 4c <= 1000
OpenStudy (anonymous):
I wanted to know if I was right
OpenStudy (mertsj):
yes. They are right except the second one should be greater than or equal because they need at least $1000 and I'm pretty sure they won't care if they make more than that.

okay so 8a + 4c >= 1000
OpenStudy (anonymous):
then I solve it?
OpenStudy (mertsj):
yes
OpenStudy (anonymous):
would you mind helping me on that part
OpenStudy (mertsj):
I would solve that second one by 4 to make the numbers smaller.
