Jen Butler has been pricing Speed-Pass train fares for a group trip to New YOrk. Three adults and four children must pay $132.Two adults and three children must $94. Find the price of the adults ticket and the price of a child's ticket.

Respuesta :

A: adults
C: children

3A+4C = $132
2A+3C= $94

2A+3C=$94
2A+3C-3C= 94-3C
2A= 94-3C
2A/2= (94-3C)/2
A= 94/2-3C/2
so, 3(47-3C/2)+4C=$132
C=$18 price of the children ticket

and by using 2A+3C=$94, C=18
2A+3*18=94
2A=40 ..... A=$20 price of the adults ticket
Good luck
