Can you please help with formulas and knowing what values to plug in to get the solutions, thank you! I attached an image with the question.

1) The present value of the revenue Boris could expect to gain from providing the training is ?

2)The present value of the net cost to Boris of providing the training is?

3) The net present value to Boris of providing the training is?

The following situation (taken in modified form from "First Problem Set, Part II") applies to questions 1 through 4. Boris' widget factory employs one widget worker who presently earns $10,000/yr. (which is equal to his MRP) . Boris is deciding whether to individually train his widget worker in a secret family widget process usable only with Boris's equipment. The training will take one year. The widget worker will work half time while training and will take a pay cut of 50%. After he finishes his training, his salary will increase to $11, 000/yr., but his marginal revenue product will rise 20%. Also, the more productive human capital input will raise the productivity of Boris' company's physical capital from 10% to 15% per year (Boris has $100, 000 of physical capital now yielding a $10 , 000 per year return) . Boris expects the direct cost of training the worker will be $1, 000. Due to a labor turnover rate of 10% per year (including deaths) and a high business failure rate of 50%/year for his type of business, Boris expects to close down the factory in two years. Ignore the uncertainty premium. Also, ignore depreciation of physical capital. The market interest rate, applicable in Boris' situation, is 10 percent. All costs and benefits are as of the end of the year
