A certain drug dosage calls for 25mg per kg per day and is divided into two doses (1 every 12 hours). if a person weighs 180 pounds, how much of the drug should they get each dosage?

We first need the weight of the person in kg.

Applying

1 lb = 0.454 kg

180 * 0.454

= 81.72 kg

The daily dosage of drug is then:

25 * 81.72

= 2043 mg

Dividing that into two doses per day:

2043 / 2

= 1,021.5 mg per dose
