Please explain the steps taken. Thank you!

Blossom Co. began operations on July 1. It uses a perpetual inventory system. During July, the company had the following purchases and sales. Calculate the average cost per unit at July 1, 6, 11, 14, 21&27. (Round intermediate calculations to 0 decimal places and final answers to 3 decimal places, e.g. $105.501.) Determine the ending inventory under a perpetual inventory system using (1) FIFO, (2) moving-average cost, and (3) LIFO. (Round average-cost per unit to 3 decimal places, e.g. 12.520 and final answer to 0 decimal places, e.g. 1,250.)
