You begin work on June 1 and work until August 31, and receive pay on the last day of the month. Your expenses for these three months are $1500/mo. At the end of September, you make a $7000 payment, and you make an identical payment at the end of January. Your expenses from September 1 through May 31 are $1000/mo. a. Draw a discrete, nondiscounted cash flow diagram for this situation. b. If you earn 4% interest, compounded monthly, on the money until it is spent, what monthly salary is required from June 1 through August 31 to break even on May 31? c. If you earn 4% interest, compounded monthly, on the money until it is spent and the salary is $4000/mo, how much would you have to earn each month from a different job from September through May to break even on May 31? d. What situation is depicted in this problem?
