The manager of a water park keeps track of the amount of money collected, m, and the number of tickets sold, t, each day. Which best describes the variables m and t?

• The variable m is the independent variable because it depends on the number of tickets sold, t.

• The variable t is the dependent variable because it depends on the amount of money collected, m, each day.

• The variable t is the independent variable because it affects the amount of money collected, m, each day.

• The variable m is independent of variable t, and variable t is independent of variable m.
