Question 1110874: to a fall musical. On the first day of ticket sales the school sold 14 Kim's school is selling tickets adult tickets and 16 student tickets for a total of $394. The school took in $324 on the second day by selling 9 adult tickets and 15 student tickets. What is the price each of one adult ticket and one student ticket? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 14A+16C=394
9A+15C=324
multiply top by 9 and bottom by -14
126A+144C=3546
-126A-210C=-4536
-66C=-990
C=15
from first, 14A+240=394
14A=154
A=11
check in second
99+225=324
child is $15
adult is $11
