Final answer:
The annual accounting (book) rate of return (ARR) based on the initial investment is 40%.
Step-by-step explanation:
The annual accounting (book) rate of return (ARR) based on the initial investment can be calculated using the formula:
ARR = Average Annual Net Income / Initial Investment × 100%
Given that the machine will produce sales of $200,000 each year and expenses amount to $80,000 per year, the annual net income can be calculated as:
Net Income = Sales - Expenses = $200,000 - $80,000 = $120,000
Using the initial investment of $300,000, we can calculate the ARR as:
ARR = $120,000 / $300,000 × 100% = 40%
So, the correct answer is 40%.
