<PRE><B>Question 1132773</B>
&lt;br&gt;
With simple interest, the amount of interest is always based on the original amount.  So the amount of interest in each year is going to be the same.&lt;br&gt;
ANSWER: The amount of interest in the 8th year is equal to the amount of interest in the 4th year.&lt;br&gt;

Added after seeing the response by tutor @MathTherapy....&lt;br&gt;
He apparently thinks he knows everything, because all his responses say &quot;accept no other answer&quot;.  Unfortunately, his answers are not always right.&lt;br&gt;
Ignore his answer on this one; it is plain wrong.&lt;br&gt;
The situation he describes, where interest for a year is based on the total amount at the beginning of the year, is precisely what describes compound interest -- NOT simple interest.&lt;br&gt;
With compound interest, the amount of interest in each year is more than the interest in the preceding year.&lt;br&gt;
But your problem involves SIMPLE interest.&lt;br&gt;
The formula for the amount of simple interest is&lt;br&gt;
I = prt&lt;br&gt;
I = interest amount
p = initial amount
r = interest rate
t = time (years)&lt;br&gt;
Let&#39;s look at a simple example -- $1000 with an interest rate of 10%.&lt;br&gt;
The interest earned in 3 years is  I = prt = ($1000)(.10)(3) = $300&lt;br&gt;
The interest earned in 4 years is  I = prt = ($1000)(.10)(4) = $400&lt;br&gt;
The interest earned IN THE 4TH YEAR is $400-$300 = $100.&lt;br&gt;
The interest earned in 7 years is  I = prt = ($1000)(.10)(7) = $700&lt;br&gt;
The interest earned in 8 years is  I = prt = ($1000)(.10)(8) = $800&lt;br&gt;
The interest earned IN THE 4TH YEAR is $800-$700 = $100.&lt;br&gt;
The interest earned in the 8th year is THE SAME AS the interest earned in the 4th year.</PRE>
