Please provide a detailed manual step by step solution for Scenario $1$ for $2\%$ interest, keep notice of the first four years of construcion. Provide detailed calculation of benefit$-$cost ratio for the Scenario $1$ only. Problem:

Use the data provided below $($taken from the original study$)$ to conduct a simple benefit cost analysis for the dam and

reservoir. The benefit$-$cost analysis is to consider a $44-$year timeframe, of which the first four years are for construction.

Table $3.$ Summary of Meridian Project Capital Costs $($S million in $2001$ dollars$)$

${?}^1$ Includes land acquisition, roads and utilities relocation, and costs associated with oil and gas developments.

Table $4.$ Summary of Meridian Project Annual Costs $($S million in $2001$ dollars$)$

Table $5.$ Summary of Meridian Project Annual Benefits $($$ million in $2001$ dollars$)$

Hydropower economic benefits are estimated to be $$\frac{50}{M}Wh.$

${?}^2$ Environmental benefits assuming "green" hydropower valued at $$\frac{20}{M}Wh.$

Using interest rates of $1)2\%$ and $2)6\%,$ conduct a benefit$-$cost analysis for the proposed Meridian Dam and express your

solutions in tabular form.
