A certain drug dosage calls for 21 mg per kg per day and is divided into two doses (1 every 12 hours). If a person weighs 181 pounds, how much of the drug should they get each dosage?

The person weighing 181 pounds should get 862.05 mg of drugs for each dose.

Step-by-step explanation:

Weight of the person = 181 pounds

= 82.1 kg

2 Dosage = 21 mg per kg per day

1 dosage = 10.5 mg per kg

For 1 kg 10.5 mg of drugs can be taken and for 82.1 kg,

= 82.1 x 10.5

= 862.05 mg of drugs can be taken

The person weighing 181 pounds should get 862.05 mg of drugs for each dose.
