b) What is the percent rate of decrease in acetaminophen each hour?

c) Six hours after taking the medication, what is the concentration of acetaminophen?

d) It is only safe to take a second dosage once the amount of acetaminophen in the blood has reached 25 mg. How many hours after the first dose can a person take a second dose of the medication?
