The graph shows the money collected at an amusement park from the sale of adult tickets.
In the graph, y represents the money collected from the sale of adult tickets, and x represents the number of adult tickets sold. Which equation describes the proportional relationship between the amount of money collected and the number of adult tickets sold?
A.
y = 52x
B.
y = 208x
C.
x = 52y
D.
x = 208y
1 answer
The correct equation would be A. y = 52x. Since the money collected is represented by y and the number of adult tickets sold is represented by x, it follows that the amount of money collected would be directly proportional to the number of adult tickets sold. In a proportional relationship, the equation would be in the form y = kx, where k is the constant of proportionality. In this case, the constant of proportionality is 52, so the equation becomes y = 52x.
