To identify:
The independent and dependent variables for each relation, used in the given statement.

Answer to Problem 7LC
In given relation, independent variable is “Data available for rest of the family members” and dependent variable is, “Data used by Mike“ .
Explanation of Solution
Given information:
Given the statement, “Mike`s cell phone is a part of a family plan. If he used more data than his share, there is a less data available for the family.
Formula/Concept used:
It is a total data available that is to be consumed by Mike`s family members. So, relation will be set between total number of members of the family and total data to be used by them. And data consumed will be based on how much each member of the family uses for his/her personal use.
Conclusion:
So, in above relation, independent variable is “Data available for the rest of the family” and dependent variable will be, “Data used by Mike”.
