Question

A certain medicine is given in an amount proportional 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

132 pounds -> 143 milligrams

1 pound -> 143/132

156 pounds -> 143/132 * 156 = 169 milligrams
