A debt of $2000 plus interest at 6% compounded monthly is due in 2 years. Another debt of $1000 plus interest at 10% compounded semi-annually is due in 5 years. If $1000 is paid at the end of 3 years, what two equal payments, one at the end of year 1 and the other at the end of year 4 will satisfy the original debt? The interest rate is now 10% compounded quarterly. Use 4 years as the focal date
