4. Change the estimated total amount of the allocation base back to 68,000 machine-hours, so that the data area of you worksheet looks exactly the same as in Requirement 2. Now change the actual manufacturing overhead cost from $504,400 to $500,500. The data area of your worksheet should now look like this: A B 1 Chapter 3: Applying Excel 2 3 Data Allocation base 4 5 Machine-hours $ 496,400 68,000 machine-hours $ 500,500 75,000 machine-hours Estimated manufacturing overhead cost Estimated total amount of the allocation base Actual manufacturing overhead cost Actual total amount of the allocation base 6 7 8 (a) By how manufacturing erhead underapplied overapplied? manufacturing overhead (b) Why is the amount of underapplied (overapplied) manufacturing overhead different from Requirement 2 above? (You may select more than one answer. Single click the box with the question mark to produce a check mark for a correct answers and double click the box with the question mark to empty the box for a wrong answers. Any boxes left with a question mark will be automatically graded as incorrect.) The predetermined overhead rate changed. The change in the actual manufacturing overhead cost directly resulted in a comparable change in the amount of underapplied (overapplied) manufacturing overhead. The change in the estimated total amount of the allocation base affected the amount of manufacturing overhead applied. 2. Change all of the numbers in the data area of your worksheet so that it looks like this: B A 1 Chapter 3: Applying Excel N 3 4 5 Data Allocation base Estimated manufacturing overhead cost Estimated total amount of the allocation base Actual manufacturing overhead cost Actual total amount of the allocation base Machine-hours $ 496,400 68,000 machine-hours $ 504,400 75,000 machine-hours 6 7 8 If your formulas are correct, you should get the correct answers to the following questions. (a) What is the Predetermined overhead rate? (Round your answer to 2 decimal places.) Answer is complete and correct. Predetermined overhead rate $ 7.30 per machine-hour (b) By how much is the manufacturing overhead underapplied or overapplied? Answer is complete and correct. Overapplied manufacturing overhead $ 43,100
