  Ignore this post (I can't seem to delete it). I had a major dumb moment and couldn't figure out why an even number plus an even number equals an even number -.-

  Actually I think there is a new way to do this; just let == be congruence, and p be the number of pennies. We know that

  p == 3(mod 4)
  p == 16(mod 25)

  Subtracting 12 on 3(mod 4) gives us p == -9(mod 4), and subtracting 25 on 16(mod 25) gives us p == -9(mod 25), so that means that p == -9(mod 100) which is the same as p == 91(mod 100).
