Nenotronic System purchases transistors each year as components in minicomputers. The unit cost of each transistor is N$10, and the cost of carrying one transistor in inventory for a year is N$3. Ordering cost is N$30 per order. Assume that Nenotronic operates on a 200-day working year and using the equation: Q=(2DS/H), what are: i. the optimal order quantity. ii. iii. the expected time between orders. the expected number of orders placed each year.
