A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?
iVinArrow [24]
I'll use my own formula (similar to yours tho)

A=P(1+ \frac{r}{n})^{nt}
A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years


so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so

2P=P(1+ \frac{0.12}{4})^{(4*t)}
divide both sides by P
2=(1+ \frac{0.12}{4})^{(4*t)}
simplify
2=(1+ 0.03)^{4t}
2=(1.03)^{4t}
take the ln of both sides
ln(2)=ln(1.03)^{4t}
ln(2)=4tln(1.03)
ln(2)=t(4ln(1.03))
divide both sides by 4ln(1.03)
\frac{ln(2)}{4ln(1.03)}=t
use calculator
5.86244=t
