Prepare a master production schedule for industrial pumps in the manner of the following table. Use the MPS rule to "schedule production when the projected on$-$hand inventory would be less than $10$ without production." Suppose that there are currently $64$ pumps in inventory and a production lot size of $70$ pumps is used. $($Leave no cells blank $-$ be certain to enter $"0"$ wherever required.$)$
