Question

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 120 milligrams of Medication A with 132 milligrams of Medication B. However this week, the doctor said to only use 121 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?

Answer 1

Answer: 109 milligrams of Medication A.

Explanation: If last week was 132 milligrams of Medication B and 120 milligrams of Medication A. Then Medication B has is 12 milligram more then Medication A. So you would do 121 milligrams minus 12 milligrams to get Medication A for this week.
