What is the Independent and Dependent Variable?

Jacob's marble collection, c, varies over time, t. Jacob started a marble collection on Monday. He increased his collection by the same ammount each day, but on Wednesday, he gave some away.

Independent Variable _____________

Dependent Variable _____________



Can anyone solve this?

4x - (x - 3) = 15



Thanks!!What is the Independent and Dependent Variable?
If marble collection varies with time - the marble collection is dependent on time. Therefore, the marble collection is the dependent variable. As time is not going to be affected by the size of the marble collection - time is the independent variable.



x=4



4x4 - (4-3) is the same as saying: 16-1
