Find Half-Life of Morphine & Kool-Aid Powder in Blood/Water

[ayahouyee]

(a) The half-life of morphine in the bloodstream is 3 hours. Suppose that there's
initially 0.4 mg of morphine in the system, how long does it take until there's
only 0.01 mg of morphine remaining in the bloodstream?

(b) Suppose that there is initially x0 (0 is a subscript) grams of Kool-Aid powder in a glass of water.
After 1 minute there are 3 grams remaining and after 3 minutes there is only 1
gram remaining. Find x0 (0 is a subscript) and the amount of Kool-Aid powder remaining after 5 minutes.

Thanks in advance!
