Better Bottles, Inc. uses a periodic inventory system and has provided its current inventory information. The Controller has asked you to prepare a comparison of the Ending inventory and Cost of Goods Sold totals for three different inventory costing methods.Periodic FIFO, LFO, and Weighted-Average. Here are some tips for using Excel: - Cell Reference: Allows you to fefer to data from another cell in the worksheet. If you entered "=B5" into a blank cell, the formulo would output the value from cell B5. - Basic Math Functions: Allow you to use the basic math symbols to perform mathematical functions. You can use the following keysit (plus sign to add), - (minus sign to subtract). "(asterisk sign to multiply), and / (forward slash to divide). For example, If you entered "84+85 in a blank cell, the formula would add the values from those cells and output the result. - SUM Function: Allows you to refer to multiple cells and adds all the values. You can add individual cell references or ranges. If you entered "=SUM(C4, C5, C6)" into a blank cell, the formula would output the result of adding those three separate cells. Similarly, if you entered "=5UM(C4:C6)", the formula would output the same result of adding those cells. 1. Use the Open Excel in New Tab button to lounch this question. 2.

Better Bottles, Inc., uses a periodic inventory system and has the following information available 3) Using Periodic Weighted Average, first calculate the cost per unit using the formula below. Next, apply that same cost per unit to calculate both the Ending Inventory and Cost of Goods Sold. (Use cells A4 to D10 from the given information to complete this question.) WeightedAverageCost=NumberofUnitsAvailableforSaleCostofGoodsAvailableforSale= 4) Use the given information and your calculated numbers to complete the Cost of Goods Sold Equation below for all three inventory methods. (All numbers should be positive.) (Use cells A4 to D10 from the given information to complete this question.) (Use cells A4 to D10 from the given information to complete this question.) 4) Use the given information and your calculated numbers to complete the Cost of Goods Sold Equation below for all three inventory methods. (All numbers should be positive.) (Use celis A4 to D10 from the given information to complete this question.)
