(Leverage) Your friend presents you with the following deal: You can buy a box for $9, decorate it at a cost of $1, and sell it in 1 year for $11.

a. You have $100 to invest in the boxes (and decorations). What are your profits assuming the deal goes through? What is the return in percentage on your investment?

b. Suppose that in addition to your own $100, you can borrow $900 at 5% interest. The whole amount of $1,000 will be invested in boxes.

What are your profits assuming the deal goes through? What is the return in percentage on your investment?

c. Assume you borrowed the $900 carrying a 5% interest rate for the deal period, bought the boxes and decorated them, but you have just found out that the market price of the decorated boxes has dropped to $8.5. What are your profits/losses in dollars? What is the return in percentage on your investment?
