Question

A good doctor recommends that a person who weighs 65 pounds be given 200

milligrams of medicine. If the dosage were proportional to a person's weight, how
many milligrams of medicine would the doctor recommend for a person who
weighs 96 pounds?

Answer 1

9514 1404 393

Answer:

295 mg

Explanation:

The proportion can be written ...

dose/(96 lb) = (200 mg)/(65 lb)

dose = (96/65)(200 mg) ≈ 295.4 mg . . . . . multiply by 96 lb, cancel lb units

The doctor might recommend 295 mg for a 96-pound patient.
