Answer :
Final answer:
A person weighing 130 pounds would require approximately 186.6 milligrams of medicine. This was determined by setting up and solving a proportion using the given information.
Explanation:
This problem can be solved by setting up a proportion. Let's assume that 'x' is the unknown amount of medicine required for someone weighing 130 pounds. We know that 195 pounds corresponds to 279 milligrams of medicine. The proportion can be set up as 195/279 = 130/x. To solve this proportion for 'x', we can cross-multiply and divide.195 * x = 279 * 130, x = (279 * 130) / 195. When we calculate this, 'x' comes out to be approximately 186.6 milligrams. Hence, a person weighing 130 pounds would require around 186.6 milligrams of the medicine, so the correct answer is (c) 186.6 milligrams.
