Answer:
A 4-month weighted moving average forecast for July would be 137.50.
Explanation:
Note: This question is not complete as the appended information is not provided. To complete the question, the appended information is therefore before answering the question as follows:
Month Actual Demand
January 120
February 95
March 100
April 25
May 200
June 25
The explanation of the answer is now provided as follows:
The most recent month = June
The month preceding the most recent month = May
The month preceding that one = April
Last month = March
Therefore, we have:
Forecast for July = (June actual demand * 30%) + (May actual demand * 50%) + (April actual demand * 40%) + (March actual demand * 20%) = (25* 30%) + (200 * 50%) + (25 * 40%) + (100 * 20%) = 137.50
Therefore, a 4-month weighted moving average forecast for July would be 137.50.
