Question

Richard sells frozen juice cups at a fair for $1.25 each. The amount of money, m, he makes each day and the number of cups, c, that he sells are related. Which variable is the independent variable and which is the dependent variable? Complete the table.

Independent Dependent

Answer 1

Independent: the number of cups, c, that he sells

Dependent: the amount of money, m, that he makes each day

Explanation:

* The independent variable determines the value of the dependent variable. The number of cups of frozen juice that Richard sells each day determines the amount of money that he makes each day.

* Side note: For your information, the linear equation that models this relationship would be m = 1.25 c. You would graph that as y = 1.25 x, and since x is independent while y is dependent, you know that c is independent and m is dependent.

* Good luck completing the table! I would help out with that if I could see it!
