a)

First we have to find the payment, assume it is made at the end of each year

15000000= pay( 1 - 1.12^-5)/.12

pay = 4161145.98

Paym# interest principal Balance

1 1800000.00 2361145.98 12638854.02

2 1516662.48 2644483.45 9994370.52

3 1199324.46 2961821.52 7032549.01

4 843905.89 3317240.10 3715308.91

5 445837.07 3715308.91 0.00

not bad,

now do b) the same way

your payment equation will be

25000000 = pay( 1 - 1.0625^-6)/.0625
