A company incurred $120,000 in fixed manufacturing overhead costs and $70,000 in variable manufacturing overhead costs during a particular period. If the company produced 18,000 units during that period, calculate the total manufacturing overhead cost and the cost per unit. Conduct a detailed analysis of fixed and variable overhead costs, exploring their behavior patterns and implications for cost management and budgeting. Discuss strategies for optimizing overhead cost allocation and utilization to enhance operational efficiency and profitability.
