Accounting Rate of Return (ARR) = Incremental Net Income / Average Investment
--> Incremental Net Income (Incremental Income minus Incremental Cost):
A) Incremental Income = Decrease in annual operating cost = 138600 - 91300 = 47300
B) Incremental Cost = Increase in Depreciation = 20000-15000 = 5000
Therefore, Incremental Net Income = Incremental Income - Incremental Cost = 47300-5000 = 42300
--> Average Investment = (Initial Investment + Salvage Value)/2
Therefore, Average Investment = (160000+0) / 2 = 80000
--> Therefore, ARR = Incremental Net Income / Average Investment
Therefore, ARR = 42300 / 80000 = 0.5288 = 52.88%
