Essay

Use mathematical induction to prove that for all integers $n \geq 3$ ,
$$2 \cdot 3 + 3 \cdot 4 + \cdots + ( n - 1 ) \cdot n = \frac { ( n - 2 ) \left( n ^ { 2 } + 2 n + 3 \right) } { 3 } .$$

Understand how to compute the total units and costs to be accounted for in a production process.

Differentiate between physical units and cost units in the production cost report.

Analyze the impact of activity-based costing (ABC) and its limitations.

Identify the basic similarities and differences between job order cost and process cost systems.

Definitions:

Fixed Manufacturing Overhead

Costs incurred during the production process that do not vary with the level of production, such as rent for factory buildings, salaries of plant managers, and depreciation of manufacturing equipment.

Budget Variance

The variance between what was expected to be spent or earned, according to the budget, and the real amount that was spent or received.

Predetermined Overhead Rate

A rate used to allocate manufacturing overhead to individual products or job orders, based on a specific activity base, such as labor hours or machine hours.

Fixed Component

The portion of total costs that remains unchanged regardless of the level of production or business activity.
