I would appreciate it if you could clearly state the formulas you used and the operations you performed.

An investor borrowed 336263 PLN. Find how many equal annual payments of 89000 PLN should be made if the annual rate of interest is 10%. Solve the problem of non-integer number of payments. Show three different methods.

( I don't know more about the question.)
