PISA: Trinity Is in the Hospital and Receives an Injection

PISA: Trinity is in the hospital and receives an injection of penicillin. Her body gradually breaks the penicillin down so that one hour after the injection only 60% of the penicillin will remain. The pattern continues: At the end of each hour only 60% of the penicillin that was present at the end of the previous hour remains active. Suppose Trinity is given a dose of 300 milligrams of penicillin at 0800 hours. Complete this table showing the amount of penicillin that will remain active in Trinity's body at intervals of one hour from 0800 until 1100 hours.
