Final answer:
PQB Inc.'s financial activities are framed within a job-order costing system that is influenced by changes in labor costs and manufacturing decisions, such as the choice between labor and machines for production efficiency.
Step-by-step explanation:
The transactions given for PQB Inc. reflect the financial activities of a company using a job-order costing system to track manufacturing costs and overhead related to the production of unique movie props. When firms face higher wage demands from unions or changes in labor costs, they can choose to shift towards using more physical capital and less labor to maintain or increase labor productivity, affecting the total production costs. The example provided with the home exercise cycle production plans represents how increases in wages from $16 to $20 per hour can alter the company's decision whether to employ more labor or invest in more machines. PQB Inc.'s year-end activities include purchasing of materials, payroll, incurring utility and depreciation costs, incurring manufacturing overhead costs, applying overhead to production, completing production of movie props, sales, collections from customers, and payments to suppliers.
