Final answer:
To find out how much medicine a 172-pound person can have, we can use a proportion to calculate the medicine amount based on the weight of the 192-pound person. The answer is approximately 1018.5 mg.
Step-by-step explanation:
To find out how much medicine a 172-pound person can have, we can use the ratio of weight to medicine. First, we find the ratio of weight to medicine for the 192-pound person:
192 pounds → 1141 mg
Next, we set up a proportion to find the medicine amount for the 172-pound person:
172 pounds → x mg
We can cross multiply and solve for x:
192 pounds * x mg = 172 pounds * 1141 mg
x mg = (172 pounds * 1141 mg) / 192 pounds
x mg ≈ 1018.5 mg
Therefore, a 172-pound person can have approximately 1018.5 mg of medicine.
