A doctor prescribes 100 milligrams of a therapeutic drug that has decayed to 40% of its original quantity after 8 hours (ie. after 6 hours, only 40% remains). Assume the quantity of the drug is modeled by an exponential equation. Give a function that describes the quantity of the drug (in milligrams) after t hour and determine how long until only 5% of the drug remains? Please use a calculator to get the final answer and round down to two decimal places.
