Answer:
Children = 215 Tickets
Explanation:
Givens
Total amount = 3280
Total Tickets = 785
Cost of 1 Child Ticket (C) = 2$
Cost of 1 Adult Ticket (A) = 5$
Equations
2C + 5A = 3280
C + A = 785 Multiply this by 2
Solution
2C + 2A = 1570
2C + 5A = 3280
Subtract
- 3A = -1710 Divide by -3
A = 570
C + A = 785
C = 785 - 570
C = 215
Check
215 * 2 + 570 * 5
430 + 2850 = 3280 which is what the total was.
