the required parts are a part of 2 main questions. please explain.

Kingsport Containers Company makes a single product that is subject to wide seasonal variations in demand. The company uses a job-order costing system and computes plantwide predetermined overhead rates on a quarterly basis using the number of units to be produced as the allocation base. Its estimated costs, by quarter, for the coming year are given below: Direct materials Direct labor Manufacturing overhead Total manufacturing costs (a) Number of units to be produced (b) Estimated unit product cost (a) + (b) First $ 200,000 80,000 220,000 $ 500,000 160,000 $ 3.13 Quarter Second Third $ 100,000 $ 50,099 40,000 20,000 196,000 184,000 $ 336,000 $ 254,000 80,000 49.000 $ 6.35 Fourth $ 150,899 60,899 ? S? 120, 889 5? $ 4.20 Management finds the variation in quarterly unit product costs to be confusing. It has been suggested that the problem lies with manufacturing overhead because it is the largest element of total manufacturing cost. Accordingly, you have been asked to find a more appropriate way of assigning manufacturing overhead cost to units of product Required: 1. Assuming the estimated variable manufacturing overhead cost per unit is $0.30, what must be the estimated total fived manufacturing overhead cost per quarter? 2. Assuming the assumptions about cost behavior from the first three quarters hold constant, what is the estimated unit product cost for the fourth quarter? 3. What is causing the estimated unit product cost to fluctuate from one quarter to the next? 4. Assuming the company computes one predetermined overhead rate for the year rather than computing quarterly overhead rates calculate the unit product cost for all units produced during the year. Required 1 Required 2 Required 3 Required 4 Assuming the estimated variable manufacturing overhead cost per unit is $0.30, what must be the estimated total fixed manufacturing overhead cost per quarter? Fixed manufacturing overhead cost Required 1 Required 2 Required 3 Required 4 Assuming the assumptions about cost behavior from the first three quarters hold constant, what is the estimated unit product cost for the fourth quarter? (Do not round intermediate calculations and round the "Unit product cost" to 2 decimal places.) Unit product cost Required 1 Required 2 Required 3 Required 4 What is causing the estimated unit product cost to fluctuate from one quarter to the next? The fixed portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost increases as the level of production decreases because the fixed overhead is spread over fewer units The fixed portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost decreases as the level of production decreases because the fixed overhead is spread over fewer units. The variable portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost increases as the level of production decreases because the variable overhead is spread over fewer units. The variable portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost decreases as the level of production decreases because the variable overhead is spread over fewer units. Required 1 Required 2 Required 3 Required 4 Assuming the company computes one predetermined overhead rate for the year rather than computing quarterly overhead rates, calculate the unit product cost for all units produced during the year. (Do not round intermediate calculations and round the "Unit product cost" to 2 decimal places.) Unit product cost Vhite Company has two departments, Cutting and Finishing. The company uses a job-order costing system and computes a predetermined overhead rate in each department. The Cutting Department bases its rate on machine-hours, and the Finishing Department bases its rate on direct labor-hours. At the beginning of the year, the company made the following estimates: Direct labor-hours Machine-hours Total fixed manufacturing overhead cost Variable manufacturing overhead per machine-hour Variable manufacturing overhead per direct labor-hour Department Cutting Finishing 8,700 71,000 2,790 $ 380,000 $ 552,000 $ 3.00 $ 3.75 68,809 Required: 1. Compute the predetermined overhead rate for each department. 2. The job cost sheet for Job 203, which was started and completed during the year, showed the following: Direct labor-hours Machine-hours Direct materials Direct labor cost Department Cutting Finishing 3 10 84 3 $ 790 $ 390 $ 57 $ 190 Using the predetermined overhead rates that you computed in requirement (1), compute the total manufacturing cost assigned to Job 203 3. Would you expect substantially different amounts of overhead cost to be assigned to some jobs if the company used a plantwide predetermined overhead rate based on direct labor-hours, rather than using departmental rates? Required 1 Required 2 Required 3 Compute the predetermined overhead rate for each department. (Round your answers to 2 decimal places.) Cutting Department Predetermined overhead rate Finishing Department per MH per DLH Required 1 Required 2 Required 3 Using the predetermined overhead rates that you computed in requirement (1), compute the total manufacturing cost assigned to Job 203. (Round intermediate calculations to 2 decimal places and final answer to the nearest dollar amount.) Total manufacturing cost Required 1 Required 2 Required 3 Would you expect substantially different amounts of overhead cost to be assigned to some jobs if the company used a plantwide predetermined overhead rate based on direct labor-hours, rather than using departmental rates?
