Please answer all

1) Where do interest rates come from? Why would you be an idiot (excuse the harsh language) if you paid $1 today to receive $1 at the end of a year? In other words, a startup tech firm wants to borrow $1 from you right now to fund Virtual Reality research. The firm promises to pay you back $1 at the end of the year. What are the reasons (and I need at least two here) that you would find such a deal totally unacceptable, and would demand more than $1 back from that startup at the end of the year? 2) a) In what way does this journal entry: XXX Accounts Receivable Revenues XXX tend to overstate assets and income? Remember, the typical big firm makes this journal entry thousands of times a day. b) How do we try to fix that problem under Generally Accepted Accounting Principles
