Final answer:
The correct answer is C. The internal rate of return on this branch expansion is approximately 23%.
Step-by-step explanation:
To calculate the internal rate of return (IRR), we need to find the discount rate at which the present value of the cash inflows equals the initial investment.
Using the formula for present value of an annuity, we calculate:
Initial investment = $1.2 million
Present value of cash inflows = $235,000/(1+0.12) + $412,300/(1+0.12)^2 + $665,000/(1+0.12)^3 + $875,000/(1+0.12)^4
IRR is the discount rate that makes the present value of cash inflows equal to the initial investment. We can use the IRR function in Excel or financial calculator to find the rate, which is approximately 23%. Therefore, the internal rate of return on this branch expansion is approximately 23%.
