Question: Company X uses fermentation to produce a valuable industrial chemical. A startup company approaches X with a novel microbe that will increase the yield of the chemical, so that profits will increase by an estimated $14.0k/mo. The startup company wishes to sell the rights to use the microbe for a seven-year period, at a price of $480k.
Engineers at company X estimate the increased production will entail additional maintenance, costing $12.0k in year 2, $14.0k in year 4, and $17.0k in year 6 of the project.
1. What would a cash flow diagram of the project, from the standpoint of Company X?
2. How can I calculate the present value of the project, assuming a 13.0% annual interest rate?
3. Using Excel, make a well-formatted graph of the project present value vs. interest rate, for interest rates ranging from 0 to 30% APR.
1. Here, the additional maintenance cost is spread throughout the year. For eg., $12,000 in year-2 is spread across 12 months of year 2 at $1,000 per month

2.
We use the NPV function in excel
Discount rate = 13%/12 ( Since there are 12 periods per year and 13% is the annual interest rate.

We get the Net Present Value of the project = $276,561.0098
3. We calculate the NPV for different annual interest rates
