need helo with formulas please!

Variance Analysis using Excel's ABS, IF and Basic Math Functions Patterson, Inc has provided details of its actual cost data for the month. The Controller has asked you to compute the basic vaitances and the impact of those variances on unit costs. 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, 4 was entered the formula would output the result from cell D4, or 275 in this example, Basic Moth 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-F4+G5" was entered the formulo would add the values from those cells and output the result, or 14.70 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-SUMD405) was entered the formula would output the result of adding those two separate cells, or 5.45 in this example. Similarly, if in a blank cell -SUMD4:05) 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 5.45 in this example. ABS function: Allows you to return the absolute value of a number or calculation. You can reference any cell to display its absolute value or surround another formula with the ABS function to return the final result as an absolute value. From the Excel Simulation below, if in a blank cell you entered ABSFZ-GBT" Excel will first calculate the subtraction of F7-68 that results in -0.20. Then, the ABS portion of the formula returns the absolute value of the subtraction result, which would be 0.20 In this example IF function: Allows you to test a condition and return a specific value is the result is true and different value if the result is false. The syntax of the IF function 15Ftest condition.value_l_true value_ittaise and specific considerations need to be made when using this function The test condition argument is an evaluation of the status of a cell, such as if the value of a cellis greater than, less than or equal to another number on cell. The value. Crve and value false arguments will return any specific result for each option, such as another cell reference, a value, or text. Throughout the entire equation, if text is being used in the tesl.condition, value_t_true, or value_It_faise arguments then the text itse it should be entered in quotations so that Excel will recognize the text as a string of text" instead of another function. From the Excel Simulation below. If in a blank cel-IFF13>20. "Total Cost Per Unit is good. Tocal Cost Per Unit is bad was entered the formula would output the resuit of the value_true since the test condition would be result as true, or in this case the text Total Cost Per Unitis goodExcel processes the IF function by separating it out into separate parts. First the test.condition - Excel thinks, find cell 13 and determine if the value is greater than 20 Once Excel determines if the result of that test_condition is TRUE OR FALSE I will return the 20. "Total Cost Per Unit is good. Tocal Cost Per Unit is bad was entered the formula would output the resuit of the value_true since the test condition would be result as true, or in this case the text Total Cost Per Unitis goodExcel processes the IF function by separating it out into separate parts. First the test.condition - Excel thinks, find cell 13 and determine if the value is greater than 20 Once Excel determines if the result of that test_condition is TRUE OR FALSE I will return the
