Final answer:
A budget is a financial plan expressing management's expected revenues and expenses, whereas a standard is a unit cost benchmark used for controlling and assessing performance. The correct distinction option 3) is that a budget expresses a total amount, while a standard expresses a unit amount.
Step-by-step explanation:
The difference between a budget and a standard is often misunderstood. A budget represents management's plans for the future, outlining expected revenues and expenditures, and serves as a financial representation of the company's goals. It expresses a total amount and has both tactical and strategic implications.
On the other hand, a standard refers to a predetermined benchmark that reflects what costs should be on a per-unit basis. Standards are used for cost control by comparing actual costs with what should have been incurred, making them crucial for variance analysis.
Option 3 in the student's question is correct: a budget expresses a total amount, while a standard expresses a unit amount. Budgets and standards are both integral parts of the cost accounting system, guiding decision-making and performance assessment.
