Final answer:
The estimated accounting (book) rate of return on the initial investment is 96.00%.
Step-by-step explanation:
To calculate the estimated accounting (book) rate of return on the initial investment, we need to divide the average annual after-tax income by the initial investment cost. In this case, the machine is expected to generate a constant after-tax income of $80,000 per year for 12 years, so the total after-tax income over the 12 years is $80,000 x 12 = $960,000. The initial investment cost is $1,000,000.
Therefore, the estimated accounting (book) rate of return is $960,000 / $1,000,000 = 0.96 or 96%.
Rounded to two decimal places, the estimated accounting (book) rate of return is 96.00%, which corresponds to option D).
