ALL ANSWERS MUST BE IN EXCEL FORMULAS!!

I understand how to use all other formulas except for the DDB function, I have looked it up everywhere and I still can't figure this out and I really need help. Sending out a very big thank you to whoever helps me with this!!! (:

Sullivan Ranch Corporation has purchased a new tractor and has provided you with the information related to the purchase. The Controller has asked you to calculate the depreciation for the new piece of equipment using different methods. Straight-Line depreciation Units of Production depreciation, and Double Declining Balance depreciation. 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"-38" was entered the formula would output the result from cell B8, or 360 in this example, Absolute Reference: Allows you to maintain the original cell reference when a formula is copied to another cell. The cell reference is "locked" by putting a dollar sign ($) before the column and row references. By default a cell reference is relative, so when you copy a formula to another cell the values update based on a relative reference. For example, if you copy the formula -38.89" from cell Ctto cell C2, the formula in cell C2 will relatively update to be --B9.810 since the copied formula moved down one cell , the formula cell references also moved down one cell Conversely, by adding the absolute cell reference "locks to the equation, the formula will not change when copied to any other cell. For example, $B$8+$B$9" written in cells copied to cell C2, the formula in cell C2 will remain$858+$B$9" You can also use a mixed cell reference by only "locking the column or row only ($88 or B$) which locks that specific column or row and the other reference becomes a relative reference and "moves" with the formula as its copied to another cell. For example, if you copy the formula 858-89" from cell Ci to cell C2 the formula in cell C2 will update to be-858-810" since the copied formula moved down one cell, the formula cell relative references also moved down one cell, but the absolute "locked" reference remained the same Bosis 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), * fasterisk sign to multiply) and/(forward stash to divide) From the Excel Simulation below, if in a blank cell"-810-811" was entered the formula would add the values from those cells and output the result or 570 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 add individual cell references or ranges to utilize this function. From the Excel Simulation below, if in a blank cell SUM(B8, 89,810)" was entered the formula would output the result of adding those three separate cells, or 980 in this example Similarly, in a blank cell -SUM(B8 810)" was entered the formula would output the same result of adding those cells, except they are expressed as a range in the formula, and the result would be 980 in this example, SIN function: Allows you to calculate the depreciation of an asset using the straight-line depreciation method. The syntax of the SLN function is --SLN cost salvage life and outputs the depreciation for one period. The cost argument is the initial cost of SLN function: Allows you to calculate the depreciation of an asset using the straight-line depreciation method. The syntax of the SLN function is ESLN(cost salvage Me) and outputs the depreciation for one period. The cost argument is the initial cost of the asset the salvage argument is the salvage value at the end of the life of the asset. The life argument is the number of periods over which the asset is being depreciated, also called the usefut lite DDB function: Allows you to calculate the depreciation of an asset using the double-declining balance method. The syntax of the DDB function is DDB(cost salvage life, period, factor and outputs the depreciation for one period. The function must include the first four arguments and has a fifth optional argument the cost argument is the initial cost of the asset. The salvage argument is the salvage value at the end of the life of the asset The me argument is the number of periods over which the asset is being depreciated also called the useful life. The period argument is the period for which you want to calculate the depreciation and must use the same units as the Me argument. The factor argument is the rate at which the balance declines when omitted is assumed to be 2 (the double-declining balance method) Tota Prepare the following Double-Declining-Balance depreciation schedule by using the Excel DDB FUNCTION (fx) to calculate Depreciation Expense for Years 1-4 in the Depreciation Expense column.
