What two equations can be written from the information in this problem if "x" equals the number of tickets purchased early, and "y" equals the number of tickets purchased the day of the show?
Tickets for a school play cost $5 if you buy them early, and $7 if you buy them the day of the show. If 200 tickets are sold, and the total amount of money from ticket sales was $1340, how many tickets were purchased early?
A. x + y = 1340
5x + 7y = 200
B. 12x = 1340
x + y = 200
C. x + y = 200
5x + 7y = 1340
D. x + y = 200
7x + 5y = 1340

x = # of tickets purchased early
y = # of tickets purchased on the day of the show
if you can only pick those two options, and if 200 tickets are sold, then x+y = 200. Agreed?
That takes care of the quantity, now develop the 2nd equation using cost to determine the complete answer.
