30% of tickets sold were kids tickets, selling at \$4. The rest were sold at \$8.50.
30% of the tickets sold by a movie theater for the Friday night show were children's tickets at \$4 each. The rest of the tickets were sold at the full price of \$8.50. The movie theater collected \$252 for the children's tickets. How many tickets did they sell in all? How do you know?

C = the number of children's tickets sold
A = the number of full-price tickets sold
4C + 8.5A = 252.00 (Equation 1). \$252 is the total amount taken in.
C + A = total tickets sold -- the total number of tickets must be the sum of the two types of tickets.
C = 0.3 (C + A) -- you know that the number of children's tickets equals 30&#37; of the total
0.7C = 0.3A (Equation 2) -- Simplified from the above.

Using Equation 1 and Equation 2, solve for C and A.
