Help! Please provide any diagrams, calculations. I'm very confused

Jane is an inventor, working for the ACME Gadget Company in research and development.She recently proposed the development of an advanced technology, but it was deemed too risky for R&D at ACME.However, ACME has agreed that if Jane successfully develops the technology on her own, ACME will acquire a license to use the technology for a period of 10 years.To develop the technology will require an initial expenditure of $250,000 now and an additional expenditure of $150,000 at the beginning of each of the next 2 years. When the patent is approved at the beginning of Year 4 (end of year 3), it is expected to be licensed to the ACME Gadget Company for an upfront fee of 100,000 plus an additional fee of $90,000/year for the next 9 years. At that time the product that uses the technology will be replaced by a new model.
