Final answer:
The project should be accepted based on the payback period, internal rate of return (IRR), and simple rate of return methods, but it should be rejected based on the net present value (NPV) method.
Step-by-step explanation:
A. Payback period: To calculate the payback period, we need to determine the time it takes for the cumulative cash flows to equal or exceed the initial investment. In this case, the cumulative cash flows at the end of each year are: $10,000, $12,400, $17,200, $20,400, $23,600, $26,400.
The payback period is the point in time when the cumulative cash flows reach or exceed the initial investment of $10,000. In this case, it takes 3 years, so the project should be accepted.
B. Internal Rate of Return (IRR): The IRR is the discount rate that makes the net present value (NPV) of the project equal to zero.
To calculate the IRR, we find the discount rate that makes the present value of the cash inflows equal to the present value of the initial investment. In this case, the IRR is approximately 40%, which is higher than the required rate of return of 8%.
Therefore, the project should be accepted.
C. Simple Rate of Return: The simple rate of return is the annual net income divided by the initial investment. In this case, the net income for each year is: $2,400, $4,800, $3,200, $3,200, $2,800, $2,400.
The simple rate of return for each year is: 24%, 48%, 32%, 32%, 28%, 24%. Since the simple rate of return is above the required rate of return of 8% for each year, the project should be accepted.
D. Net Present Value: The net present value is the sum of the present values of the cash inflows and outflows. To calculate the net present value, we discount the cash flows at the required rate of return of 8%.
In this case, the present value of the cash flows is: $9,259.26, $1,851.85, $3,703.70, $2,469.14, $2,469.14, $2,145.35. The net present value is the sum of these values minus the initial investment of $10,000, which is approximately -$1,000. Since the net present value is negative, the project should be rejected.
