GPT 3.5
To solve this problem, we can create a proportion:
(60 mg / 7.5 mL) = (x mg / 3.5 mL)
Cross-multiplying, we get:
7.5 mL * x mg = 60 mg * 3.5 mL
Simplifying, we find:
7.5x = 210
Dividing both sides by 7.5, we find:
x = 28
Therefore, the patient is given 28 mg of phenobarbital elixir.
(60 mg / 7.5 mL) = (x mg / 3.5 mL)
Cross-multiplying, we get:
7.5 mL * x mg = 60 mg * 3.5 mL
Simplifying, we find:
7.5x = 210
Dividing both sides by 7.5, we find:
x = 28
Therefore, the patient is given 28 mg of phenobarbital elixir.
