Answer:
It is easy to calculate the half-life as 36 hours.
Looking at the graphic, we see that we will need the bottom formula
Ending Amount = Beginning Amount / 2^n
Where "n" is the number of half-lives which = 52 hours / 36 hours = 1.4444444 half-lives.
Ending Amount = 100 mg / 2^1.444444444
Ending Amount = 100 / 2.71258
Ending Amount = 36.74336230689
or rounding that off, it's about 36.743 milligrams
