Once in farmers field a new variety can give a farmer higher yields for a few years before they are replaced. Farmers invest in breeding programs through check-offs. Now Suppose you invest $ 1000 today (ie. 2021) in a durable asset and you have a 5% discount rate. If you had to wait 10 years into future to an annual benefit what would be your B/C ratios NPV, IRR if you received the following stream of benefits in the following years: Year Amount Amount Discount PV PV NPV B/C Received Received Paid Factor Cost Benefit 2021 1000 2031 $400 2032 $400 2033 $400 2034 $400 2035 $400 Total Discount rate= 0.05 IRR= 4b. Explain how the delay in receiving benefits reduces the NPV of the investment. 4c. Explain how the durable nature of your investment affects your B/C ratio
