I posted a question yesteraday and got an answer. There is a second part to the question

Problem 6-4A^A Periodic: Alternative cost flows P3

Refer to the information in Problem 6-3A and assume the periodic inventory system is used.

Required

Compute cost of goods available for sale and the number of units available for sale.

Compute the number of units in ending inventory.

Compute the cost assigned to ending inventory using (a) FIFO, (b) LIFO, (c) weighted average, and (d) specific identification. (Round all amounts to cents.)

Compute gross profit earned by the company for each of the four costing methods in part 3.

Analysis Component
