Chapter 7.2, Problem 37E
Caffeine After an individual drinks a beverage containing caffeine, the amount of caffeine in the bloodstream can be modeled by an exponential decay function, with a half-life that depends on several factors, including age and body weight. For the sake of simplicity, assume the caffeine in the following drinks immediately enters the bloodstream upon consumption.
37. An individual consumes an energy drink that contains caffeine. If 80% of the caffeine from the energy drink is still in the bloodstream 2 hours later, find the half-life of caffeine for this individual.
