An investment carrying a current cost of $120,000 is going to generate $50,000 of revenue for each of the next three years. To calculate the internal rate of return we need to:
A. find the interest rate at which the present value of $150,000 for three years from now equals $120,000. B. find the interest rate at which the sum of the present values of $50,000 for each of the next three years equals $120,000. C. calculate the present value of each of the $50,000 payments and multiply these and set this equal to $120,000. D. subtract $120,000 from $150,000 and set this difference equal to the interest rate.
