Question

A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 150 pounds requires 144 milligrams of medicine. What is the weight of a patient who requires 174.72 milligrams of medicine?

Answer 1

150/144 = x/174.72

x = 150(174.72)/144 = 182 pounds

(big clue it's right: it came out even with some not so even numbers-- use a calculator)
