5 We are using simple exponential smoothing to predict monthly electric shaver sales at Hook’s Drug Store. At the end of October 2006, our forecast for December 2006 sales was 40. In November 50 shavers were sold, and during December 45 shavers were sold. Suppose a  0.50. At the end of December, 2006, what is our prediction for the total number of shavers that will be sold during March and April of 2007?
