There are 500 mg of caffeine in a can of red-bull. The biological half-life of caffeine is 5 hours.
Write an equation that models f(x), the amount of caffeine remaining in the body, given x the number of half lives passed.
Q: HOW MUCH CAFFEINE IS REMAINING IN THE BODY AFTER 30 HOURS??
f(x) = 500(1/2)x
30 hours --> each half life is 5 hours, so 6 half lives pass in 30 hours.
f(6) = 500(1/2)6 = 7.8125 mgs of caffeine.
