The local business will donate $5.00 for every 10 tickets sold. Let x represent tickets sold, and y represent dollars donated. Student A claims that the equation is y = 2x. Student B claims that the equation is y = 1

2

x. Explain who is correct.

If we let x be the number of ticket sold and y be the amount in dollars donated then, the equation would be,

x = 2y

We can check our answer by substituting the given,

10 = 2 (5)

10 = 10

The equation can also be written as,

y = (1/2) x

Thus, Student B is correct.
