The following table gives the average cost, C (in dollars), of a gallon of gas over the last several years, t. Round answers to three decimal places. Year, t Cost ($), C0.18 1960| 1970 0.25 0.36 1980 1990 2009 2013 1.19 1.34 2.05 1.98 1950 a. Find the equation of the line of best fit for the cost as a function of time. (Let 1950 = 0, 1960 = 10, etc.) C(t) = 0.03x+0.012 %3D b. According to the model (part a) what is the average annual increase in the price of gas? (give you answer with three decimal places) $ .975 c. Use the model (part a) to estimate the cost of gas in 2020. $ 2.30
