Question

John purchased 8 tickets to a talent show and spent $25. he bought a combination of child tickets for $3 each and adult tickets for $4 each. how many child tickets did john purchase

Answer 1

Adult tickets (A): $4

Child tickets (C): $3

Total Cost:      4A + 3A = 25 → 1( 4A + 3A = 25)  → 4A + 3A = 25                

Total Tickets:    A +  C  = 8   →  -4(A + C = 8)       → -4A - 4C = -32

                                                                                          -C  = -8

                                                                                            C = 8

Answer: 8 child tickets
