Answer:
i = 0.06
n = 108
Explanation:
Rate per period:
This is the interest rate, as a decimal.
In this question, the interest rate is 6%. As a decimal, this is 0.06.
So i = 0.06
Number of periods:
The compounding happens monthly.
So 1 period is 1 month.
The payments are made for 9 years, and each year has 12 months.
9*12 = 108
So n = 108R
