Question

Students sold 275 tickets for a fundraiser at school. Some tickets are for children and cost $3, which the rest are adult tickets that cost $5. If the total value of all tickets sold was 1,025, how many of each type of ticket was sold

Answer 1

Make a system of equation
(C + A = 275)5
3C + 5A = 1,025
5C + 5A = 1,375
Subtract (elimination method)
-2C = -350, divide by -2
C = 175 children tickets
275 - 175 = 100 adult tickets
Solution: 175 children tickets and 100 adult tickets
