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 90 milligrams of Medication A with 63 milligrams of Medication B. However this week, the doctor said to only use 35 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?

Answer 1

Given:

The Last week proportion is

`\begin{gathered} A=90 \\ \\ B=63 \end{gathered}`

This week proportion is

`B=35`

Find-:

How many milligrams of madication A

Explanation-:

The proportion is same for both week

`((A)/(B))_{\text{ Last week}}=((A)/(B))_{\text{ This week}}`

So, the value is:

`\begin{gathered} (90)/(63)=(A)/(35) \\ \\ A=(90)/(63)*35 \end{gathered}`

The A is:

`\begin{gathered} A=(90)/(63)*35 \\ \\ A=(3150)/(63) \\ \\ A=50 \end{gathered}`

The medication A is 50 milligram for this week
