A company is planning to purchase 90,800 units of a particular item in the year ahead. The item is purchased in boxes each containing 10 units of the item, at a price of $200 per box. A safety inventory of 250 boxes is kept. The cost of holding an item in inventory for a year (including insurance, interest and space costs) is 15% of the purchase price. The cost of placing and receiving orders is to be estimated from cost data collected relating to similar orders, where costs of $5,910 were incurred on 30 orders. It should be assumed that ordering costs change in proportion to the number of orders placed. 2% should be added to the above ordering costs to allow for inflation. Assume that usage of the item will be even over the year. etermine the following: The quantity that must be ordered to minimise total cost. How often should the items be purchased? A business has inventory of material A of 400 units valued at $2.50 per unit September 1. During the month of September, the movements of material A were as follows: September 5 , issue 250 units at $5.00 per unit September 10, receipt 500 units at $2.50 per unit September 15 , issue 340 units at $5.50 per unit September 18, receipt 400 units at $2.70 per unit September 27 , issue 600 units at $6.50 per unit a) Determine the cost of purchases, cost of issues, and the closing stock valuation using the FIFO method of stock valuation b) If expenses for the month of September was $15,550, what is Net Income? c) Identify three (3) features of the LIFO method stock valuation
