Jarrett was selling tickets at local carnical. The tickets cost 2.00 for adults and 1.50 for children. How many of each kind of ticket did he sell if he sold a total of 300 tickets for $525?

Answer 1

K+A=300
1.5K+2A=525

multiply the first equation by 2, then subtract the second equation, and you get...

.5K=600-525
K=150 tickets
A=150 tickets
