<PRE><B>Question 151818</B>
Simple interest earned (I) can be found by the formula:
{{{I=Prt}}}
where P is the principal, r is the annual interest rate,and t is the number of years that the principal will be invested.
In this problem:
P=6500
r=3 3/4%=3.75%
I=975
Substituting into the formula, we have
975 = 6500*3.75%t
Solving the equation for t, we obtain:
975 = 65*3.75*t
{{{t = 975/(65*3.75)}}}
t = 4
So choose option C.
