The S&OP team at Kansas Furniture, has received estimates of demand requirements as shown in the table. Assuming one$-$time stockout costs for lost sales of $$125$ per unit, inventory carrying costs of $$30$ per unit per month, and zero beginning and ending inventory, evaluate the following plan on an incremental cost basis:

Plan A: Produce at a steady rate $($equal to minimum requirements$)$ of $1,000$ units per month and subcontract additional units at a $$70$ per unit premium cost. Subcontracting capacity is limited to $800$ units per month. $($Enter all responses as whole numbers$).$
