Question

Justin is taking an​ anti-inflammatory drug and the instructions say that the patient must receive 8 mg for each 16 kg of body weight. If Justin weighs 259 ​lb, what dosage should he​ receive?

Answer 1

58.86 mg

Explanation:

8 mg = 16 kg

1 kg = 2.2 lb

use substitution

8 mg = 16 (2.2 lb)

8 mg = 35.2 lb

8 mg / 35.2 lb = x mg / 259 lb

2072 = 35.2 x

x = 58.86 mg
