Children's tickets to a movie cost $7. Adult tickets cost $12. If 275 tickets were sold for a total of $2490.00, how many of each type were sold?

Let adult A and children C
A + C = 275
12A + 7C = 2490
A = 275 -C
12(275- C) + 7C = 2490
3300 -12C + 7C = 2490
3300 -5C = 2490
3300-3300 -5C = 2490 - 3300
-5C = -810
C = 162
A = 113
