Explanation / Answer
Workings:
Let the discount rate be r.
Present value of a perpetity = Perpetuity / r. = $ 17,000 / r.
Present value of an ordinary annuity = Annuity x Present Value Interest Factor of an Annuity = Annuity x [ { 1 - ( 1 / 1+r ) n } / r ] = 30,000 * [ { 1 - ( 1/ 1+ r)18 } / r ]
At indifference point ,
17,000 / r = 30,000 x [ { 1 - ( 1 / 1 + r ) 18 } / r ]
r = 4.75 %.
Discount rate 4.75 %
