Final answer:
To calculate a 30% increase in a patient's medication dosage of 270mg, you find 30% of 270mg (which is 81mg) and add it to the original amount, resulting in a new dosage of 351mg.
Step-by-step explanation:
A patient who needs a 30% increase in their medication dosage is currently taking 270mg. To calculate the new dosage, you perform a calculation to find 30% of the current dosage, and then add that to the original amount.
First, calculate 30% of 270mg:
30% of 270mg = 0.30 × 270mg = 81mg
Now, add this increase to the original dosage to determine the new dosage:
270mg + 81mg = 351mg
Therefore, after a 30% increase, the patient's new medication dosage would be 351mg.
