The correct answer is option A.
The expected average rate of return for the proposed investment is 19.49%.
Average Investment = (Initial Cost + Residual Value) / 2
That is, Average investment becomes $450,200/2 = $225,100.
Now, Estimated average annual income = Total net income / Useful life
That is, Estimated average annual income = $175,480/4 = $43,870.
Average Rate of Return = Estimated Average Annual Income / Average
Therefore,
Average rate of return = ($175,480/$225,100)*100 = 19.48%.
