Answer:
The patient will need 140 pills for 7 days.
Explanation:
Amount of medicine prescribed = 300 mg/day
Amount of medicine in 1 pill = 15 mg
Let the number of pills required in 7 days be x.
Total amount of medicine to be consumed in 7 days :
300 mg/day × 7 days= 2100 mg
Number of pills × 15 mg = 2100 mg
[tex]x\times 15 mg=2100 mg[/tex]
[tex]x=\frac{2100 mg}{15 mg}=140 [/tex]
The patient will need 140 pills for 7 days.
