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

Student B is correct.
