The half-life of caffeine in the body is about 5 hours. The average cup of coffee has 100 mg. of caffeine. While cramming for an exam. Priya drank 4 cups of coffee. a) Write a function, C(h), which calculates how much caffeine is left in Priya's body after h hours. b) Priya estimates that she will not be able to fall asleep until she has less than 30 mg. of caffeine left in her body. How many hours will it take for this to happen? c) The average cup of green tea has 40 mg. of caffeine. Rewrite the equation from part (a) as if Priya been drinking green tea instead of coffee. d) Using the equation from part (e), how many hours will it be until Priya is able to fall asleep?
