A firm practices a pure chase strategy. Production last quarter was $1,033.$ Demand over the next four quarters is estimated to be $1,027,938,1,084,$ and $925.$ Hiring cost is $$19$ per unit, and layoff cost is $$6$ per unit. Over the next year, what will be the sum of hiring and firing costs?

Input should be an exact number $($for example, $5$ or $10).$
