The independent quantity is the number of kilowatt-hours used (the input to the calculation).  The dependent quantity is the amount charged, called the dependent quantity because it &quot;depends&quot; on the value of the independent quantity.  This is also referred to as the function value.  You were given the unit rate of change.  Hint:  Look for something with the word &quot;per&quot; in it, as in &quot;some amount per unit&quot;.
