Explanation:

• Interest Rate: In finance, the interest rate is indeed the "price" of borrowing (what borrowers pay for funds) and also a rate of return on an investment (what lenders or investors earn). Commissions on stock transactions, bank account - management costs, and government taxes on financial transactions are different concepts.
• Minimum Wage: A minimum wage is a price floor. It is a legal requirement that employers cannot pay employees less than a specified hourly rate. It is not a standardized salary for all entry - level workers (as different entry - level jobs can have different minimums in some cases), not just a recommendation, and it is a minimum, not a maximum.
• Usury Laws: Usury laws are specifically designed to set an upper limit on the interest rate that lenders can charge. Tax - rate determination for investments, financial - reporting standards, and banking - fee regulations are not the main focus of usury laws.

2. a price floor that makes it illegal for an employer to pay employees less than a certain hourly rate
