Answer:
9,974.80 units
Step-by-step explanation:
Exponential smoothing forecast for January = (Actual demand in December - forecasted demand in December)*Smoothing constant + Forecasted demand in December
Exponential smoothing forecast for January = (10,687-9,500)*0.4 + 9,500
Exponential smoothing forecast for January = 1,187*0.4 + 9,500
Exponential smoothing forecast for January = 474.8 + 9,500
Exponential smoothing forecast for January = 9,974.80 units
