A patient is given 800 mg of acetaminophen. The half-life of acetaminophen is about three hours. Write an exponential model of the form P(t) = that represents the amount of acetaminophen in the patient's bloodstream t hours after the medicine is administered. Use the model to determine how many milligrams of acetaminophen will be in the patient's bloodstream if the patient is given a second dose of 800 mg four hours after the first dose. Round your answer to one decimal place. (PLS don't put fake answers... Like actually)
