The post by @VFBundy looks strange, because his answer for constant interest formula is lower than daily interest.
It is not correct, and the correct answer for constant interest should be (slightly) more than for daily interest.
The cause is in using too few significant digits in the number " e ".
My answer for the constant interest is $63173.38, when I use e = 2.71828.
My notice is not to nitpick, but to restore the right order of values in the answer.
------------
One more notice: the correct name for the "constant interest rate" in this context is the "continuous interest".
