This equation is a direct variation. If y increases, x increases. The constant of variation is 4 I think. Hope that helped.

Answer:the number of student tickets that were sold is 85
the number of adult tickets that were sold is 65
Step-by-step explanation:
Let x represent the number of student tickets that were sold.
Let represent the number of adult tickets that were sold.
MCHS sold 150 tickets at the last basketball game. This means that
x + y = 150
Student tickets cost $3 and adult tickets cost $5. If they sold $580 worth of tickets, it means that
3x + 5y = 580 - - - - - - - - - - -1
Substituting x = 150 - y into equation 1, it becomes
3(150 - y) + 5y = 580
450 - 3y + 5y = 580
- 3y + 5y = 580 - 450
2y = 130
y = 130/2 = 65
Substituting y = 65 into x = 150 - y, it becomes
x = 150 - 65 = 85
