Computation involving different cost flow assumptions. Harris Companys raw material purchases during September, its first month of operations, were as follows:

	Quantity	Cost per Pound	Total Costs
9/1 Purchase	1,500 pounds	$4.50	$ 6,750
9/5 Purchase	4,000 pounds	4.60	18,400
9/14 Purchase	2,500 pounds	4.90	12,250
9/27 Purchase	3,500 pounds	5.15	18,025
9/29 Purchase	2,000 pounds	5.25	10,500
Total Goods Available for Sale	13,500 pounds		$65,925

The inventory at September 30 was 2,500 pounds. Assume a periodic inventory system. Compute the cost of the inventory on September 30 and cost of goods sold for September under each of the following cost flow assumptions:

1. FIFO b. LIFO c. Weighted Average
