A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 104 pounds requires 169 milligrams of medicine. What is the weight of a patient who requires 224.25 milligrams of medicin
104 / 169 = x / 224.25......104 lbs to 169 mg = x lbs to 224.25 mg cross multiply because this is a proportion (169)(x) = (104)(224.25) 169x = 23322 x = 23322 / 169 x = 138 lbs <==
