Correct Answer is ["7.5"]
Explanation
Step 1: Determine how many mL are needed for one dose.
The order is 30 mg.
Available concentration is 40 mg per 5 mL.
Use a proportion:
40 mg : 5 mL = 30 mg : x mL
Solve for x:
x = (30 × 5) / 40 = 150 / 40 = 3.75 mL
Step 2: Multiply by 2 doses per day:
3.75 mL × 2 = 7.5 mL
Answer: 7.5 mL
