Maria's House of Pancakes uses a weighted moving average method to forecast pancake sales. It assigns a weight of 50% to the previous month's demand, 30% to demand two months ago, and 20% to demand three months ago. If sales amounted to 1000 pancakes in May, 2200 pancakes in June, and 3000 pancakes in July, what should be the forecast for August? *
