D is the answer I believe it is.
The interest due on the first payment is
.. I = Prt
.. I = 110,000*.055*(1/12)
.. I = 504.17
Then the decrease in principal resulting from the first payment is
.. 568.00 -504.17 = 63.83
and the new balance is
.. $110,000.00 -63.83 = $109,936.17
Level, x 1 0.8 0.65
time, y 0 1 2
The graph is not a straight line, it is curved. You can observe this only if you include the point (1,0), which is the level at the begining (100%)
The y - intercept is the full level, at the beginning of the experiment.
I dont understand, is it 15% over 15 % or just 15 % or is it 293$ over 293$ or is it just 239.
If 
is a factor of 
, then 
is a root of .
Therefore
