The$$ S&OP team at Kansas$$ Furniture, led by David$$ Angelow, has received estimates of demand requirements as shown in the table. Assuming$$ one$-$time stockout costs for lost sales of $$$$100$ per$$ unit, inventory carrying costs of $$$$25$ per unit per$$ month, and zero beginning and ending$$ inventory, evaluate these two plans on an incremental cost$$ basis:

Plan$$ A: Produce at a steady rate$($equal to minimum$$ requirements$)$ of $1,000$ units per month and subcontract additional units at a $$$$65$ per unit premium cost. Subcontracting capacity is limited to $800$ units per month. $($Enter all responses as whole numbers$).$
