Your friend wants to borrow $1,000 for a year. When you ask about an interest rate on the loan, he says that he shouldn't have to pay interest because "it's a risk-free loan... you know I'm good for it... even if I can't come up with the money, my parents will pay you back." You are certain that his parents would pay you if he did not. Analyze his argument... is he correct? If so, explain why. And if not, explain why not
