Frosty’s Snow Cones uses a weighted moving average method to forecast snow cone sales. It assigns a weight of five to the previous month's demand, three to demand 2 months ago, and one to demand 3 months ago. If sales amounted to 1,000 snow cones in May, 2,200 snow cones in June, and 3,000 snow cones in July, what should be the forecast for August?
