Question

A certain medicine is given in an amount proportion to a patient’s body weight. Suppose a patient weighing 132 pounds requires 143 milligrams of medicine. What is the amount of medicine required by a patient weighing 156 pounds?

Answer 1

Answer:

  169 mg

Step-by-step explanation:

The ratio of medicine quantity to body weight is the same for both patients, so ...

  amount/(156 lb) = (143 mg)/(132 lb)

Multiply by 156 lb:

  amount = (143 mg)(156/132) = 169 mg

The patient requires 169 mg of medicine.
