Sasha is thinking about investing 20.000 dollars in a company, which offers him a fiveyear plan of divident payment at the end of each year: At the end of the first year, he will get 2000 dollars. At the end of the second year, he will get 4000 dollars. At the end of the third year, he will get 6000 dollars. At the end of the fourth year, he will get 6000 dollars again, and at the end of the last year of payment plan, he will get 5000 dollars.
