Answer :
Final answer:
The original dosage before the doctor increased it by 20% was 15cc.
Explanation:
The subject of this question is mathematics, specifically dealing with the topic of percentages. The problem given here is that a doctor increased a patient's dosage by 20% and that the new dosage is 12cc. We're tasked with finding out what the original dosage was before the increase. When the new dosage (after increase) is 100%, the original dosage (before increase) would be 100% - 20% = 80%. To find the original dosage, we need to set up an equation where 80% of the original dosage is equal to 12cc, the dosage after the increase.
To set up this equation, we can say: 0.80 (Original Dosage) = 12. Solving this gives us the original dosage: Original Dosage = 12 / 0.80 = 15cc. So, the original dosage that the doctor prescribed was 15cc.
