P1: Your chemical firm has a new bioplastic that it is selling which should have a market life of 10 years. The first costs of producing this new plastic are $15.0 million. The initial raw material costs will be $4.3 million per year, with a constant 3% rate of increase per year. Production costs for labor, energy, and facility maintenance are initially $1.8 million per year, with a 2% rate of increase as the production facility ages.
