Answer:
28 month (approx)
Explanation:
Given
Present value = $470
Monthly Payment = $20
Interest Rate = 15% annual = 15% / 12 = 1.25% monthly
=0.0125
<h3>
![Present Value = PMT [\frac{1-(1+i)^{-n}}{i}] \\470 = 20 [\frac{1-(1+0.0125)^{-n}}{0.0125}]\\470/20 = [\frac{1-(1+0.0125)^{-n}}{0.0125}]\\23.5 \times 0.0125 =1-(1+0.0125)^{-n}\\1-0.29375= (1+0.0125)^{-n}\\0.70625 = (1+0.0125)^{-n}\\0.70625 =(1.0125)^{-n}\\0.70625= \frac{1}{(1.0125)^{n}}\\(1.0125)^{n}=1.4159292\\n=28(approx)](https://tex.z-dn.net/?f=Present%20Value%20%3D%20PMT%20%5B%5Cfrac%7B1-%281%2Bi%29%5E%7B-n%7D%7D%7Bi%7D%5D%20%5C%5C470%20%3D%2020%20%5B%5Cfrac%7B1-%281%2B0.0125%29%5E%7B-n%7D%7D%7B0.0125%7D%5D%5C%5C470%2F20%20%3D%20%5B%5Cfrac%7B1-%281%2B0.0125%29%5E%7B-n%7D%7D%7B0.0125%7D%5D%5C%5C23.5%20%5Ctimes%200.0125%20%3D1-%281%2B0.0125%29%5E%7B-n%7D%5C%5C1-0.29375%3D%20%281%2B0.0125%29%5E%7B-n%7D%5C%5C0.70625%20%3D%20%281%2B0.0125%29%5E%7B-n%7D%5C%5C0.70625%20%3D%281.0125%29%5E%7B-n%7D%5C%5C0.70625%3D%20%5Cfrac%7B1%7D%7B%281.0125%29%5E%7Bn%7D%7D%5C%5C%281.0125%29%5E%7Bn%7D%3D1.4159292%5C%5Cn%3D28%28approx%29)
