Cipro is an antibiotic taken to combat many infections, including anthrax. Cipro is ltered from the blood by the kidneys. Each 24-hour period, the kidneys lter out about one third of the Cipro that was in the blood at the beginning of the 24-hour period.

a. Assume a patient was given only a single 500-mg dose. Use a difference equation to construct a table of values listing the concentration of Cipro in this patient's blood at the end of each day.

b. Nowassume that the patient must take an additional 500 mg per day. Use a difference equation to construct a table of values listing the concentration of Cipro at the end of each day.

c. Compare and interpret these two tables.
