Question

A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 153 pounds requires 249 milligrams of medicine. What is the amount of medicine required by a patient weighing 102 pounds?

Answer 1

mg required per pound = 249/153 = 1.63mg

Therefore medicine required= 102 *1.63= 166.26g

Answer 2

Answer: 166 milligrams

Explanation:

Given : A certain medicine is given in an amount proportional to a patient's body weight.

A patient weighing 153 pounds requires 249 milligrams of medicine.

Let x be the amount of medicine required by a patient weighing 102 pounds, then we have the following equation:-

`(x)/(102)=(249)/(153)\\\\\Rightarrow\ x=(249*102)/(153)=166`

Hence, the amount of medicine required by a patient weighing 102 pounds = 166 milligrams.
