The King of Pancakes uses a weighted moving average method to forecast pancake sales. It assigns a weight of 3 to the previous month’s demand, 2 to demand two months ago, and 1 to demand three months ago. If sales amounted to 1100 pancakes in May 2500 pancakes in June, and 3200 pancakes in July, approximately, what should be the forecast for August?
