4. Prepare an appropriate analysis for each of the items below. (16 points) A) Slick Real Estate Shelters, Inc., advertised that its special tax-shelter partnerships "earn 21% for the investor." An independent analysis of the actual figures (obtained from a prior partner after considerable effort) showed that an individual who invested $100,000 would receive a projected return of $310,000 at the end of the tenth year from date of the investment. Is the advertised rate of return correctly stated or underor overstated? Explain. B) A couple has an 8 percent mortgage on their new home, which at the current rate of payment will be fully paid off in 14 years. If they decide to double their annual payments to $48,000 (from $24,000 ), how long will it take them to pay off the mortgage? Assume that mortgage payments are made at the end of every six months
