Answer: The level of the dose be after 3 hours= 0.03125 mg.
Step-by-step explanation:
General exponential decay equation :
, where A = initial value , r= rate of decay , x =Time period.
Here, drug’s effectiveness is decreasing exponentially.
AS per given , we have
A= 250 mg
x=3
r= 95% = 0.95
Then, 
Hence, the level of the dose be after 3 hours = 0.03125 mg.
Check the picture below.
now, since we know what "f" is, let us use the CNT triangle with the small COR one.
