Question 3. You want to borrow $100,000 from your local bank to buy a new sailboat. You can afford to make monthly payments of $1,750, but no more. Assuming monthly compounding, what is the highest rate you can afford on a 72-month APR loan?

Question 4. A local finance company quotes an interest rate of 25 percent on one-year loans. So, if you borrow $30,000, the interest for the year will be $7,500. Because you must repay a total of $37,500 in one year, the finance company requires you to pay $37,500/12, or $3,125 per month over the next 12 months. Is the interest rate on this loan 25 percent? What rate would legally have to be quoted? What is the effective annual rate?
