When a drug is administered orally it takes some time before the blood concentration reaches its maximum level. After that time, concentration levels decrease. When 500 milligrams of procainamide is administered orally, one model for a particular patient gives blood concentration C, in milligrams per liter, after t hours as

C = 2.95(e−0.7t − e−7t).

What is the maximum blood-level concentration, and when does that level occur? (Round your answers to two decimal places.)
