Given the following results of a linear model predicting the price of a car, write out the full model using the general form y=bo+b1x1+b2x2...
What is:
Price = $23,727 - $209*age - $0.07*miles

Given that a modeling exercise generates the model
Price = $23,727 - $209*age - $0.07*miles
What is the price of the car if the age is 2 and the miles are 25000?
What is $21,559?
