A drug is administered to a hospital patient intravenously. The initial amount of the drug administered is 700 milligrams. The drug is metabolised and hence removed from the body at a rate of 40 percent per hour, that is, each hour the amount of drug remaining in the body reduces by a factor of 0.6

Calculate, to the nearest integer, the amount of drug remaining in the body (in milligrams) after 8 hours.
