The optimal order quantity (Economic Order Quantity) that Rusty Pipe should order each time is 441 units.
The economic order quantity (EOQ) is the optimal cost-effective quantity that a company can order to reduce its annual inventory costs.
The EOQ is the ideal order size that will satisfy the annual demand without insufficient or excessive inventory.
The EOQ formula is the square root of (2 x annual demand x ordering cost) /holding cost.
Annual demand = 12,950 units
Ordering cost = $15 per order
Holding or carrying cost per unit = $2
EOQ = square root of (2 x 12,950 x 15)/$2
= square root of 194,250
= 441 units
Thus, Rusty Pipe can optimally order 441 units each time it places an order.
