Solution :- Present worth of an expenditure = 85 / (1 + 0.20)3 + 85 / (1 + 0.20)4 + 85 / (1 + 0.20)5 + 85 / (1 + 0.20)6 + 85 / (1 + 0.20)7 + 85 / (1 + 0.20)8.
= 85 / (1.20)3 + 85 / (1.20)4 + 85 / (1.20)5 + 85 / (1.20)6 + 85 / (1.20)7 + 85 / (1.20)8
= 85 / 1.728 + 85 / 2.0736 + 85 / 2.48832 + 85 / 2.985984 + 85 / 3.5831808 + 85 / 4.29981696
= 49.19 + 40.99 + 34.16 + 28.47 + 23.72 + 19.77
= $ 196.30 (approx).
