$(1)$ Sensitivity Analysis. The expected cash flow forecasts are given below in Table $1$ for Otobai Company's Motor Scooter project.

Table $2$ lists three possible scenarios for each relevant variable. The cost of capital for Otobai Co$.$ is r$=10\%.$ For simplicity, when

considering uncertainty, assume that all variables remain constant $($in billion Yen$),$ except the one you are changing, and Table $3$ lists

all the NPVs in each possible situation.

Please verify the NPV for at least two situations. I will provide solutions for the two worst NPVs$.$
