To solve the problem of determining how much of the 22nd payment will go to interest, we can follow the steps below:
### Step-by-Step Solution:
1. Identify the given values:
- The outstanding principal at the time of the 22nd payment is \[tex]$1,581.
- The annual interest rate is 9%.
2. Convert the annual interest rate to a monthly interest rate:
- The monthly interest rate is the annual interest rate divided by 12.
- Monthly Interest Rate = Annual Interest Rate / 12
- Monthly Interest Rate = 0.09 / 12 = 0.0075
3. Calculate the interest portion of the 22nd payment:
- Interest for the 22nd payment is determined by multiplying the outstanding principal by the monthly interest rate.
- Interest for 22nd Payment = Outstanding Principal * Monthly Interest Rate
- Interest for 22nd Payment = \$[/tex]1,581 0.0075
4. Perform the multiplication:
- = \[tex]$1,581 0.0075 = \$[/tex]11.8575
5. Round the result to the nearest hundredth:
- Rounding \[tex]$11.8575 to the nearest hundredth gives us \$[/tex]11.86
Therefore, the amount of the 22nd payment going towards interest is [tex]$\$[/tex]11.86$.
