Question

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, percent each hour. Write a function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected.

Answer 1

C(t)= D-(30Dt/100)

Explanation:

C(t)= 120-(30*120*1h)/100 C(t)=84

C(t)= 120-(30*120*2h)/100 C(t)=48

C(t)= 120-(30*120*3h)/100 C(t)=12
