Answer 1

The answers are:

A) $954.83

B) $143,739.01

Step-by-step explanation:

If you are taking a 30 year fixed rate mortgage for $200,000 with an interest rate of 4%, you are going to pay 360 equal monthly installments of $954.83. At the end of the 30 years, you will have paid a total of $343,739.01, out of which $143,739.01 will amount to interest.

The easiest way to calculate this is by using a mortgage calculator, you can choose from several free options online. But if you want to do it manually, you would need to elaborate a 360 month payment schedule.
