Question 1059139: Jen Butler has been pricing Speed-Pass train fares for a group trip to New York. Three adults and four children must pay
$ 85.
Two adults and three children must pay
$ 60.
Find the price of the adult's ticket and the price of a child's ticket. Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let a be adults, and c be children. Then:
3a+4c=85
2a+3c=60
So;
6a+8c=170
6a+9c=180
c=10
a=15
Adults pay $15 each; children pay $10 each. ☺☺☺☺
