Answer 1

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

$x\times 15 mg=2100 mg$

$x=\frac{2100 mg}{15 mg}=140$

The patient will need 140 pills for 7 days.
