The half life of aspirin in a person's bloodstream is about 15 minutes.
If a person's bloodstream contains 256 milligrams of aspirin, how much of that aspirin will remain after 60 minutes?
:
The decay formula
A = Ao*2^(-t/h)
where:
A = resulting amt after t minutes
Ao = initial amt
t = time
h = half life of substance
:
A = 256*2^(-60/15)
A = 25y*2^-4
A = 256*.0625
A = 16 mg remain after 60 min
