    This reminds me of the amoritzation problems from my calculus class in college. The periodic interest rate was rounded down a bit more than what I would have used if I were to do this in Excel. I’m too lazy to do that, so I’m using a simple calculator and rounding my answers… am I right?

    1. 3 1/2 years
    2. $950
    3. $300
    4. 12 months.
    5. $720
    6. $70
