Kevin's body metabolizes caffeine at a rate of 14.4% per hour (so the amount of caffeine in Kevin's body decreases by 14.4% each hour).

  1. If Kevin consumes a cup of coffee with 86 mg of caffeine in it, how long will it take for Kevin's body to metabolize half of the 86 mg of caffeine?

  2. If Kevin consumes an energy drink with 200 mg of caffeine in it, how long will it take for Kevin's body to metabolize half of the 200 mg of caffeine?

  3. If Kevin consumes a cup of coffee with cc mg of caffeine in it, how long will it take for Kevin's body to metabolize half of the cc mg of caffeine? (Hint: your answer will be a numerical value.)
