Calculating with the Solver. Suppose last month’s forecast for a
product was 2,000 units. In the meantime, three market changes have
occurred that affect this forecast. A) The price of the product has
dropped, causing an expected 20% increase in sales. B) A major
sales-force training program started, causing an expected 5% increase
in sales. C) A competitor is introducing a new product, causing an
expected 15% drop in sales. Calculate the new forecast for next month.
