The manager of a movie theatre wants to know the number of adults and children who go to the movies. The theatre charges $8.00 for each adult ticker and $4.00 for each child ticket. At a showing where 200 tickets were sold, the theatre collected $1,304.
A) Write a system of equations to represent this situation.
B) How many adult tickets and how many child tickets were sold?
C) If the operating costs totaled $946.00, what is the amount of profit or loss per ticket?

Best ResponseYou've already chosen the best response.0What does our next equation have to do with? (the first one was about how many people attended)

Best ResponseYou've already chosen the best response.0the next equation needs to deal with the profits being made... right?

Best ResponseYou've already chosen the best response.0Good. each adult ticket cost 8.00 and each child cost 4.00 for a total of $1,304 so 8a + 4c = 1304

Best ResponseYou've already chosen the best response.0a + c = 200 8a + 4c = 1304 do you know how to solve this system?

Best ResponseYou've already chosen the best response.0The way you do this is to do something to one of the equations to GET RID of one of the variables. I am going to get rid of the a's... so I will need to multiply the first equation by 8 so it cancels with the +8a in the 2nd equation

Best ResponseYou've already chosen the best response.08(a + c = 200) 8a + 4c = 1304 8a  8c = 1600 8a + 4c = 1304 now add these

Best ResponseYou've already chosen the best response.0which means that c = 74?

Best ResponseYou've already chosen the best response.0Yes... so substitute in a + c = 200 a + 74 = 200 a = 126

Best ResponseYou've already chosen the best response.0Then part c. They made $1304 by selling tickets. It cost them $946 for movie rights, lights,etc. so they actually made $1304  $946 = $358 They sold 200 tickets so they made $358/200 per ticket which is $1.79 per ticket.
