Answer :
Final answer:
The amount of medicine required by a patient weighing 156 pounds is 169 mg.
The answer is option ⇒a
Explanation:
To find the amount of medicine required by a patient weighing 156 pounds, we can set up a proportion using the weights and the amounts of medicine. We know that 132 pounds is to 143 mg as 156 pounds is to x mg. By cross-multiplying and solving for x, we can find the amount of medicine required.
Using the proportion, we have:
132 pounds / 143 mg = 156 pounds / x mg
Cross-multiplying:
132x = 143 * 156
Dividing both sides by 132:
x = (143 * 156) / 132
Calculating the value of x gives us:
x = 169 mg
Therefore, the amount of medicine required by a patient weighing 156 pounds is 169 mg.
