Math Problem Statement
A machine with a current value of 40.000 Euro will be replaced after 10 years.
It is expected that the machine can be sold by that time for 4.000 Euro.
A new machine will cost 52.000 Euro at that time.
In order to have sufficient money available to replace the machine after 10 years, the same amount of money is transferred into a bank account at the end of each year.
The bank account gives a compound interest of 6% per year during the first 8 years. During the last two twee years the account does not give any interest.
How much money must be transferred each year into the bank account?
