Q 13.6. For the machine example in the text, do both the financials and the cash-flow analysis using monthly discounting. Assume that the loan is taken at the end of the first month (with an inflow of $50), and the first interest payment of $0.42 paid in the second month. (Thus, unlike in the previous question, interest is paid during the first year.) Assume most expenses and income occur pro rata. (Warning: Unless you are a masochist, do not solve this question by hand. Use a computer spreadsheet!)
