At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter.

igomit [66]

Answer:

$c(t) = 120 [0.7]^{t}$

Step-by-step explanation:

At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter.

From that moment forward, the medicine's concentration drops by 30% each hour.

Therefore, the medicine concentration c(t) in mg/liters after t hours will be modeled as

$c(t) = c(0) [1 - \frac{30}{100}]^{t}$

⇒ $c(t) = c(0) [1 - 0.3]^{t}$

⇒ $c(t) = 120 [0.7]^{t}$ . (Answer)
