The number of pills where the patent should require for 7 days should be 140 pills.
Given that
The doctor prescribed 300 mg per day to a patient.
And, each pill contains 15 mg of the medicine.
So, for one day it should be
[tex]= \frac{300}{15}[/tex]
= 20 pills
Now the number of pills for seven days should be
[tex]= 20\ pills \times 7\ days[/tex]
= 140 pills
Therefore we can conclude that the number of pills for seven days should be 140 pills.
