A firm uses simple exponential smoothing with trend adjustment to forecast demand, "a = 0.7" and "B=0.6". The Forecast including Trend (FIT) for the 1st month of 2022 was 413 units whereas the actual demand turned out to be 457 units, the trend over that period was 21. Calculate the demand forecast including trend for the 2nd month.
