Three years ago, Andrea loaned $2000 to Heather. The principal with interest at 9% compounded semiannually is to be repaid four years from the date of the loan. Eighteen months ago, Heather borrowed another $1000 for 3 ½ years at 8% compounded semiannually. Heather is now proposing to settle both debts with two equal payments to be made one and three years from now. What should the payments be if money now earns 6% compounded quarterly?
