Process Costing and the Weighted-Average Method using Excel's SUM and Basic Math Functions Hayword, Inc. uses weighted-average costing and has two departments and has provided data related to its mixing department for the month of July. The Controller has asked you prepare a cost reconciliation report and provide the related computations. Use the information included in the Excel Simulation and the Excel functions described below to complete the task. - Cell Reference: Allows you to refer to data from another cell in the worksheet. From the Excel Simulation below, if in a blank cell, "=B5" was entered, the formula would output the result from cell B5, or 300 in this example. - Basic Math functions: Allows you to use the basic math symbols to perform mathematical functions. You can use the following keys: + (plus sign to add), - (minus sign to subtract). "(asterisk sign to multiply), and / (forward slash to divide). From the Excel Simulation below, if in a blank cell "=89+810" was entered, the formula would add the values from those cells and output the result, or 17,250 in this example. If using the other math symbols the result would output an appropriate answer for its function. - SUM function: Allows you to refer to multiple cells and adds all the values. You can odd individual cell references or ranges to utilize this function, From the Excel Simulation below, If in a blank cell ".SUM(B13,814)" was entered, the formula would output the result of adding those two seporate cells, of 737,320 in this example. Simliarly, If in a biank cell "=SUM(B13:814)" was entered, the formula would output the same result of adding those celis, except they are expressed as a range in the formula, and the result would be 737,320 in this example. Hayword, Inc, uses weighted-average costing and has two departments - mixing and packaging. The following information relates to work in the mixing department for the month of July
