Scenario $2$: The Boeing Company is considering an investment into a new safety software for their Dreamliner $787$ aircrafts. The company expects to use the software for $12$ years and the company has a MARR of $10\%$ per year, compounded annually

Assume the software costs $$781,826$ today, will generate cost savings $($i$.$e$.$ benefits$)$ of $$310,495$ at the end of each year, and will generate revenue of $$63,878$ at the end of year $5$ and $$115,353$ at the end of year $10.$ What is the benefit$-$cost ratio of the software?

Assume the software investment is cut short, and only lasts $6$ years. Use the net cash flows below to calculate the simple payback period of the six year investment. $($Note: enter your answer as the number of years; if your answer is $10\mathrm{.}25$ years, enter $"10\mathrm{.}25")\backslash$table$[[$Year $0,$$$-737,011$six$-$year
