Solution
a) We are given the future value (after 3 years) of an investment as $270. According to the question, this is compounded annually at 8% interest rate. The present value can be estimated as, PV=FV/(1+r)^t
PV= 270/(1+0.08)^3
= 270/1.26 =$214.29
Jim should place value of $214.29 today for the given opportunity.
b) Since, the future value of this investment = $270,the maximum Jim should pay is this amount itself, I.e.,$270 (which considers the case that there\'s 0 return on investment). If he pays more than that, it means he has suffered a loss, as the cost of investment will be then higher than the future yield of investment.
c) In part a), for purchasing the investment, Jim has to pay $214.29. So the rate of return = (270-214.29)/214.29 = 0.26 approx.
If the purchase amount for same investment is lower, say P < 214.29, then (270-P) > (270-214.29), giving us a higher rate of return.
