Jens just took out a loan from the bank for 18,620 dollars. He plans to repay this loan by making a special payment to the bank of 3,550 dollars in 4 years and by also making equal, regular annual payments of X for 10 years. If the interest rate on the loan is 6.13 percent per year and he makes his first regular annual payment in 1 year, then what is X, Jens’s regular annual payment?
