title: Return method, Calculation Error
body: <p>I wrote the following program:</p>
  
  <pre><code>    public double calcElectricityCO2(double avgBill,                                         double avgPrice)
      {
          return (avgBill/avgPrice)*1.37*12;
  
      } 
      public static void main(String[ ] args)  
      {
          double avgBill = 338.59;
          double avgPrice = 0.12;
          double emmision = calcElectricityCO2(avgBill,avgPrice);
          System.out.printf("Annual CO2 Emission from Electricity Usage: %1.2f %n",emmision);
      }     
  }
  </code></pre>
  
  <p>When run it reports an error on <code>double emmision = calcElectricityCO2(avgBill,avgPrice);</code> What did I do wrong there?</p>
