You and your friend are selling tickets to a charity event. You sell 7 adult tickets and 16 student tickets for $120. Your frien
d sells 13 adult tickets and 9 student tickets for $140. What is the cost of a student ticket?
1 answer:
x=adult tickets
y=student tickets
(9x+13y=212)*4= 36x+52y=848
(4X+15y=168)*9= 36x+135y=1512
subtract both equations -83y=-664
divide by -83 y=8
student tickets cost $8

Answer:
(176, 193)
Step-by-step explanation:
Well you forgot to put in the choices, but:
The difference between the numbers is 17. Let's call the smaller number x and the bigger one y
(x + y) = 369
y = x + 17
(x + (x + 17)) = 369
2x + 17 = 369
2x = 352
x = 176
y = x + 17 = 193
