Casting requires a one‑time mould cost of \(\text{₦}5{,}000\) and a per‑unit cost of \(\text{₦}150\); a single casting batch can contain up to 20 units and needs 4 days of lead time. Machining has no tooling cost, a per‑unit cost of \(\text{₦}250\), and each unit takes 0.5 day to machine. An order for 45 units must be completed within 12 days.
