Question

ACe

medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 119 pounds requires 136 milligrams of medicine.
What is the weight of a patient who requires 200 milligrams of medicine?

Answer 1

weight of the patient = 175 pounds

Explanation:

Patient body weight : medicine

119 : 136

What is the weight of a patient who requires 200 milligrams of medicine?

Let

Patient body weight = x

Patient body weight : medicine

x : 200

Equate both proportions

119 : 136 = x : 200

119 / 136 = x / 200

Cross product

119 * 200 = 136 * x

23,800 = 136x

x = 23,800 / 136

= 175

x = 175 pounds
