Answer:
111
Explanation:
Exponential Smoothing forecast for 2018 = (Alpha*Actual demand in 2017) + ((1 - Alpha)*Forecast demand for 2017: Where Alpha = 0.1, Actual demand in 2017 = 120 and Forecast for 2017 = 110
Exponential Smoothing forecast for 2018 = (0.1 * 120) + ( (1 - 0.1) * 110)
Exponential Smoothing forecast for 2018 = (0.1 * 120) + (0.9 * 110)
Exponential Smoothing forecast for 2018 = 12 + 99
Exponential Smoothing forecast for 2018 = 111
