Brewster's is considering a project with a life of $4$ years, an initial cost of $$150,000,$ and a discount rate of $15$ percent. The firm expects to sell $1,350$ units a year at a cash flow per unit of $$50.$ The firm will have the option to abandon this project after $2$ years at which time it could sell the project for $$87,500.$ At what level of sales should the firm be willing to abandon this project at the end of year $2?$

Level of sales to abandon $=$ units

The firm is interested in knowing how the project will perform if the sales forecasts for Years $3$ and $4$ of the project are revised such that there is a $75$ percent chance the unit sales will be $900,$ otherwise they expect to sell $1,650$ units per year. What is the net present value of this project given these revised sales forecasts?
