Crane Marine Products began the year with 10 units of marine floats at a cost of $11.40 each. During the year, it made the following purchases: May 5, 30 units at $16.60; July 16, 15 units at $19.80; and December 7, 20 units at $24.00. Assuming there are 25 units on hand at the end of the period, determine the cost of goods sold under (a) FIFO, (b) LIFO, and (c) average-cost. Crane uses the periodic approach. FIFO $ LIFO Average-cost Cost of Goods Sold 600 415 SA $ 507.5
