Final answer:
Given that 464 milligrams (mg) is 80% of the original dose, we can determine the original dosage by dividing 464 by 80 and then multiplying by 100 which gives 580mg. This indicates that the patient originally received a dose of 580mg on Wednesday.
Explanation:
To solve this problem, you need to find what 100% is when 80% equals 464 milligrams. This uses the principle of percentages in mathematics. So, if 464mg represents 80% of the original dosage (because the dosage was decreased by 20% on Thursday), we can find the original dosage (100%) using the relation:
464mg = 80% of original dosage
To find the 100% value, we divide 464 by 80 and then multiply by 100. In mathematical terms:
Original dosage = (464mg / 80) * 100
When you perform this calculation, you get 580 milligrams. Therefore, the patient received a dosage of 580 milligrams on Wednesday.
