Prepare an Excel worksheet that shows the Ending Inventory Balance and the Cost of Goods Sold for the year using each of the three inventory valuation methods, LIFO, FIFO, and Average Cost. You will be graded on how well your worksheet data flows. For example, if I open your worksheet and change the ending inventory number, then I expect your worksheet to also change based on the new information. Be sure to link as many cells as possible and use formulas for every calculation.
