Answer :
Final answer:
The original dosage was 3000 units.
Explanation:
To find the original dosage, we need to solve for x in the equation 128% of x equals 3840 units. We can rewrite 128% as a decimal by dividing it by 100, which gives us 1.28.
So, the equation becomes 1.28x = 3840. To solve for x, we divide both sides of the equation by 1.28: x = 3840 / 1.28 = 3000.
Therefore, the original dosage was 3000 units.
