The result should have been:

malthus=malthus/.%[[1]]

Which looks pretty much as expected. (At least it looks pretty much as I expected.)

Plotting the Malthus Solution

Now we'll plot malthus on the interval 0 ≤ t ≤ 210 in green, assigning the plot the name malthusplot so that we can use the picture again later.

The command we'll need is:

malthusplot=Plot[malthus, {t, 0,210},
  PlotStyle->RGBColor[0,1,0]]

Flip back to Mathematica and try it.

Let's go see what you should have gotten...
