Answer:
Total interest of 30 year=90000
Convert 30 years into months =30*12=360
Interest payment of each month =90000/360=250
If you shall pay this mortgage in one year=100000/12=8333.33
Total payment pay pr month=250+8333.33 =8583.33
So,
Interest payment of each month is $250
Total payment per month =$8583.33
