Question

if a hospital patient is given 50 milligrams of medicine which leaves the bloodstream at 10% per hour,how many milligram of medicine will remain in the system after 6 hours?

Answer 1

if the medicine leaves the blood stream at 10% per hour and 6 hours goes by 60% of the medicine would be gone. 60% of 50 is 30. so 30mg would have left. so there is only 20mg left.
