Help needed with part c. Please show work and formulas used to solve.

a) Using a 2-year moving average, the forecast for year 6=3,775 miles (round your response to the nearest whole number). b) If a 2-year moving average is used to make the forecast, the MAD based on this = miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.) c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.45 and 0.55 (the weight of 0.55 is for the most recent period) = nearest whole number). The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.45 and 0.55= miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.)
