Given
Rate = 10% compunded monthly
Loan Amount , P = $11900
Making payment per month = %119
Find
Remaining balance after 18 months
Step-by-step explanation
Time period = 18/12 = 3/2 years
As we know
Amount =
![\begin{gathered} P(1+((R)/(12))/(100))^(12n) \\ 11900(1+((10)/(12))/(100))^{12*(3)/(2)} \\ 11900(1+((10)/(12))/(100))^(18) \\ 11900(1+(5)/(600))^(18) \\ 11900((121)/(120))^(18) \\ 13,817.2359 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/8npbxjjuwdv4j8kf2wg466ehotz23uw0fy.png)
john pays $16 per month
so, after 18 months , he pays
![116*18=2088](https://img.qammunity.org/2023/formulas/mathematics/college/akfqmwm9vwcr4q2omgtbe6hdoiho560iy2.png)
therfore his remaining balance after 18 months = $ (13,817.2359 - 2088) = $ 11729
Final Answer
his remaining balance after 18 months = $ 11729
