Waterway Industries began the year with 12 units of marine floats at a cost of $11 each. During the year, it made the following purchases: May 5, 30 unit at $17; July 16, 19 units at $20; and December 7, 24 units at $24. Assume there are 35 units on hand at the end of the period. Waterway uses the periodic approach.

Determine the cost of goods sold under FIFO. FIFO $ Cost of good sold Determine the cost of goods sold under LIFO. LIFO $ $ Cost of good sold Calculate average unit cost. (Round answer to 2 decimal places, e.g. 5.12.) $ $ Average unit cost Determine the cost of goods sold under average-cost. Average-Cost $ Cost of good sold
