Write an equation that represents the relationship between the quantities in the table. Use x for the independent variable in your equation and y for the dependent variable in your equation. Explain what x and y represent in the context of the problem.
Tickets Purchased Cost ($)
5 60
15 180
25 300
The relationship between the number of tickets purchased (x) and the cost (y) can be represented by the equation:
y = 12x
In this equation, x represents the number of tickets purchased and y represents the total cost in dollars. This equation shows that the cost of the tickets is directly proportional to the number of tickets purchased, with each ticket costing $12.
