Average starting salaries for students using a placement service at a university have been steadily increasing. Astudy of the last four graduating classes indicates the following average salaries: Php35,000, Php31,000, Php38,500, and Php32,000 (last graduating class). Predict the starting salary for the next graduating class using a simple exponential smoothing model with a = 0.45. Assume that the initial forecast was Php30,000 (so that the forecast and the actual were the same)
