Apply the Model
Let’s revisit the original situation:
Khalid works on the weekends for his uncle’s gas company. He has been analyzing the average cost the company has charged residents for natural gas over the past six months.
Month  | 
    Price (in dollars) per 1000 cubic feet  | 
  
|---|---|

    11.78  | 
  
You  have determined that the best fit equation is
.  The residuals were  close to 0 and random, and the curve fit almost perfectly through the data  points. Now that you have a model of  best fit, you can use the model to make predictions about future trends.  Use your model to answer the following:
