Answer

Brief Explanations:

The explanatory variable is the one that is thought to influence or explain changes in another variable. The response variable is the one that responds to changes in the explanatory variable. Here, the number of text - messages sent is likely influencing the percentage of phone memory used. So the number of text messages sent is the explanatory variable and the percentage of phone memory used is the response variable.

Answer:

Explanatory variable: number of text messages sent Response variable: percentage of phone memory used
