Assume that in the year 2000, cost of the compact car averaged $ 13000 and that in 2003, cost averaged $ 15400. Suppose that relationship between year t and cost c is linear, write the formula for forecasting average cost of the compact car in future measuring variable t as years since 2000. Ensure to use lower case variables t and c. What do you forecast average cost of the compact car will be in year 2008?
