<PRE><B>Question 350131</B>
Hi,
Note: The formula for finding simple interest is: Interest = Principal * Rate * Time. 
Let t represent the time it would take to triple the Principal P
.
I = P*r*t
. 
In this case, we want the interest acculmulated to be 2P so as to triple the investment.
(2*P}= P*.14*t
2P = P*.14*t
t = (2P/( P*.14)
t = (2 /.14)
.
t = 14.285
.
check your answer
2P = P*(.14)*(14.285)
2 =(.14)*(14.285)</PRE>
