Answer:
$128,000
Step-by-step explanation:
Given that,
Factory supplies = $ 21,000 
Administrative wages and salaries = $ 118,000 
Direct materials = $ 166,000 
Sales staff salaries = $ 81,000 
Factory depreciation = $ 62,000 
Corporate headquarters building rent = $ 47,000 
Indirect labor = $ 45,000 
Marketing = $ 116,000 
Direct labor = $ 96,000 
Manufacturing overhead includes the non direct material costs and non direct labor costs. Manufacturing overhead also defined as the factory expenses or the production overhead.
Manufacturing Overhead Costs: 
= Factory supplies + Factory depreciation + Indirect labor 
 = $21,000 + $62,000 + $45,000 
 = $128,000
Therefore, the total of the manufacturing overhead costs listed above for December is $128,000.
