Answer: 15.96
Explanation:
The expected rate of return will be the Average income divided by the average cost.
It is stated that the asset has a useful life of 4 years with no residual value so at the end of 4 years it will be worth $0.
The Average Cost/ Value of the Asset is calculated as;
= (Beginning Asset value - Ending Asset Value) / 2
= (600,000 - 0) /2
= 300,000
Total Income of $191,560 for the 4 years so Average income will be,
= 191,560/4
= $47,890
Expected Average Rate of Return = 47,890/300,000
= 15.96%
