After the consumption of an alcoholic beverage, the concentration of alcohol in the bloodstream (blood alcohol concentration, or bac) surges as the alcohol is absorbed, followed by a gradual decline as the alcohol is metabolized. the function c(t) = 1.35te−2.802t † models the average bac, measured in mg/ml, of a group of eight male subjects t hours after rapid consumption of 15 ml of ethanol (corresponding to one alcoholic drink). what is the maximum average bac during the first 6 hours? (round your answer to three decimal places.)
