Can you show me how to solve for n in the equation:
60000= 38400(1.07)^n
Thank you.
Another way...
$\displaystyle 60000=38400(1.07^n)$
$\displaystyle \frac{60000}{38400}=1.07^n$
$\displaystyle 1.07^n=\frac{25}{16}$
$\displaystyle \ln 1.07^n=\ln \frac{25}{16}$
$\displaystyle n \ln 1.07=\ln 25- \ln 16$
$\displaystyle n=\frac{\ln25-\ln16}{\ln1.07}$
