sarah has a headache and decides to take 400 mgs of ibuprofen for her pain. The drug is absorbed into her system and stays in her system until the drug is metabolized and filtered out by her liver and kidneys. Every four hours, Tamara’s body removes 32% of the ibuprofen that was in her body at the beginning of that four-hour period. If she continues to take 400 mg every four hours, how much ibuprofen would be in her system after a year?
