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 140 milligrams of Medication A with 154 milligrams of Medication B. However this week, the doctor said to only use 33 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?

Explanation:

According to the problem, we can apply the following rule:

By cross-multiplication, we get the following equation:

[tex](x)154\text{ = \lparen140\rparen\lparen33\rparen}[/tex]

solving for x (the milligrams of medication A that should be mixed), we get:

[tex]x\text{ =}\frac{(140)(33)}{154}=\frac{4620}{154}=30[/tex]

we can conclude that the correct answer is:

Answer:
