The doctor increased the dosage to 128% of the original dosage. If the new dosage was 3840 units, what was the original dosage?

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.
