Hi, I need help solving for part C. Thank you.

The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven next year. The miles driven during the past 5 years are as follows:
Year
Mileage
5
3,750
a) Using a 2-year moving average, the forecast for year 6 = 3775 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 = 66.7 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 0.35 and 0.65 (the weight of 0.65 is for the most recent period) = miles (round your response to the nearest whole number).
