Final answer:
The Net Present Value (NPV) method is used to evaluate the two irrigation system options. Calculating the NPV involves discounting the cash flows at the given discount rate and subtracting the initial investment. The option with the higher NPV is the more financially favorable choice. Therefore, the selection depends on which system has the higher NPV.
Step-by-step explanation:
For the underground automatic irrigation system, the annual cash flow is the pre-tax operating cost, which is $80,000 for 20 years. The NPV can be calculated using the formula:
![\[ NPV_{\text{underground}} = -\text{\textdollar}9,200,000 + \sum_(t=1)^(20) \frac{\text{\textdollar}80,000}{(1 + 0.13)^t} \]](https://img.qammunity.org/2024/formulas/business/high-school/bez4b7r5i2xs63twgz02gzc4f2gjygnlgb.png)
Similarly, for the aboveground system, the annual cash flow is the pre-tax operating cost, which is $190,000 for 9 years. The NPV is calculated as:
![\[ NPV_{\text{aboveground}} = -\text{\textdollar}6,800,000 + \sum_(t=1)^(9) \frac{\text{\textdollar}190,000}{(1 + 0.13)^t} \]](https://img.qammunity.org/2024/formulas/business/high-school/gtfiyn98xltizc1q8atoyp9jepkzw6zg2h.png)
Compute both NPVs, and the option with the higher NPV is the more financially viable choice for the Tempo Golf and Country Club. This analysis considers the time value of money and the club's cost of capital.
