Average starting salaries for students using a placement service at a university have been steadily increasing. A study of the last four graduating classes indicates the following average salaries: $30,000, $32,000, $34,500, and $36,000 (last graduating class). Predict the starting salary for the next graduating class using a simple exponential smoothing model with a = 0.25. Assume that the initial forecast was $30,000 (so that the forecast and the actual were the same). a. $30.775 b. $31,500 c. $32,625 d. $34,375
