I need help figuring out this problem. I have been working on it for days and I cannot seem to get it. Any help would be greatly appreciated.

4. The beginning inventory and purchases of an item for the period were as follows:

Beginning inventory 6 units at $73 each
First purchase 10 units at $72 each
Second purchase 18 units at $74 each
Third purchase 10 units at $75 each

The company uses the periodic system, and there were 15 units in the inventory at the end of the period. Determine the cost of the 15 units in the inventory by each of the following methods, presenting details of your computations: (a) first-in, first-out; (b) last-in, first-out; (c) average cost.

Thank you in advance!
