Final answer:
A cost accounting system can assist a manager in determining how many and which products to produce by providing information about the cost of producing each product.
Step-by-step explanation:
A cost accounting system can assist a manager in determining how many and which products to produce. This is because the cost accounting system provides information about the cost of producing each product. By analyzing this cost information, a manager can make decisions about which products are profitable and worth producing.
For example, if the cost accounting system reveals that Product A has a higher production cost compared to Product B, the manager may decide to produce more of Product B and reduce the production of Product A to maximize profitability.
Therefore, the statement given is true. A cost accounting system can indeed assist a manager in determining how many and which products to produce.
