Problema Solution
A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 164 pounds requires 205 milligrams of medicine. What is the weight of a patient who requires 173.75 milligrams of medicine?
Answer provided by our tutors
let 'x' represent the weight of the patient
a proportional relationship means the quotients will remain equal:
164/205 = x/173.75
x = 139
the patients weight is 139 pounds
