4) A typical cup of coffee contains 100 mg of caffeine. Every hour, approximately 16% of the amount of caffeine in the body is metabolized and eliminated. Let C represent the amount of caffeine in the body in mg and let t represent the number of hours since a typical cup of coffee was consumed. (a) Write an equation where C is a function of t for a typical cup of coffee. (b) How much caffeine is left in the body after 3 hours? (c) Suppose an individual cannot sleep unless she has less than 50 mg of caffeine in her blood. How many hours after drinking coffee must she wat until she is able to fall asleep?
