Tickets to a concert cost $2 for children and $5 for adults. If 630 people attended the concert and the ticket sales totaled $2,
910, how many children attended the concert? 36 50 80 120
2 answers:
A) C + A = 630
B) 2C + 5A = 2,910 Multiplying A by -2
A) -2C -2A = -1,260 Then adding it to B
B) 2C + 5A = 2,910
3A = 1,650
A = 550
A) C + 550 = 630
Children's tickets = 80
2x+5(630-x)=2910
Solve for x
2x+3150-5x=2910
2x-5x=2910-3150
-3x=-240
X=240/3
X=80 children
