Question

What is the factor for the medicine remaining in a person with each passing hour?How much medicine will remain in a person after 4 hour?

Answer 1

Assuming Medicine remaining (in miligrams) in a person is representd by r and time is represented by t, the relationship between r and t can be determined by using two point form as,

`\begin{gathered} (r-50)/(t-0)=(50-40)/(0-1) \\ r-50=t(-10) \\ r=-10t+50 \end{gathered}`
