please help!! I'm struggling on these textbook problems! please provide explanations so I can take notes, thank you!

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 fixed 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. Complete this question by entering your answers in the tabs below. 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, Note: Do not round intermediate calculations and round your final answer to 2 decimal places. Kingsport Containers Company makes a single product that is subject to wide seasonal variations in demand. The company uses a ob-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. Management finds the variation in quarterly unit product costs to be confusing.

Complete this question by entering your answers in the tabs below. What is causing the estimated unit product cost to fluctuate from one quarter to the next? The fixed portion of the manufacturing overtiead cost is caushg the unit product costs to fuctuate. The unit product cost incroasos as the level of production decreases because the fixed overtiead is spread over fewer units.

Complete this question by entering your answers in the tabs below. What is causing the estimated unit product cost to fluctuate from one quarter to the next? The fixod portion of the manufacturing overthead cost is causing the unit product costs to fluctuate. The unit product cost increases as the level of peoduction docreases becouse the fixed overhead is spread over fewer units. The fxed portion of the manutacturing overtead cost is causing the unit product costs to fluctuate. The unt product cost decreases as the level of Droduction decreasos because the fixod overhead is spread ower fewor units. The variable portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The una product cost increases as the level of production decteases because the variable overhead is spread over fower 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. ingsport Containers Company makes a single product that is subject to wide seasonal variations in demand.

(Do not round intermediate calculations and round the "Unit product cost" to 2 decimal places.)
