<PRE><B>Question 1119587</B>
How long will it take a $1,700.00 investment to earn $350.00 in interest if it is invested at 10% compounded quarterly.
:
let q = no. of quarters for this to happen
Quarterly interest rate: 10/4 = 2.5%
:
{{{1700*(1.025^q) = 1750 + 350}}}
{{{1.025^q = 2100/1700}}} 
Using natural logs
.0247q = .2113
q = {{{.2113/.0247}}}
p = 8.55, it would take 9 quarters to make at least $350 interest
