From the given codes above can you please answer the following 4 questions. Thanks.

1. Describe how you spaced the table columns and lined them up with the numbers beneath them.

2. Why do you add the interest to the loan before you subtract the monthly payment?

3. Interest rates are quoted as a yearly rate. How do you convert them to be used to calculate the monthly interest?

4. Your program might have had fractional cents in the results. How did you get the proper number of cents displayed?
