1. **State the problem:** Calculate the payback period for a French Fry King robot used for food preparation. 2. **Formula:** The payback period is calculated as: $$\text{Payback Period} = \frac{\text{Initial Investment}}{\text{Expected Annual Net Cash Inflow}}$$ 3. **Given:** The payback period is provided as 0.65 years. 4. **Explanation:** The payback period tells us how long it takes for the investment to be recovered from the net cash inflows generated by the robot. 5. **Interpretation:** Since the payback period is 0.65 years, it means the initial investment will be recovered in less than one year, which is a quick return. 6. **Additional decision tools:** Both Net Present Value (NPV) and Internal Rate of Return (IRR) are useful for analyzing investment decisions because: - NPV accounts for the time value of money and shows the net value added by the investment. - IRR gives the rate of return expected from the investment. Therefore, both NPV and IRR are likely to be useful tools for analyzing the decision to purchase the robot. **Final answer:** The payback period is 0.65 years. Both NPV and IRR are likely to be useful tools for analyzing this decision.
