Correct Answer is B
Explanation
To determine the percentage of patients who are not elderly men or young women, we first need to find the combined percentage of patients who are elderly men and young women.
- Elderly men: 12 = 50%
- Young women: 13 ≈ 33.3%
To find the total percentage of patients who are either elderly men or young women, we add these two percentages together:
50%+33.3% = 83.3%
The percentage of patients who are not elderly men or young women is:
100%−83.3%=16.7
Therefore, the correct answer is:16.7%
Correct Answer is A
Explanation
To determine if the nurse has enough medication, we need to calculate the total amount of medication used and compare it to the one-ounce vial.
- Morning Dose:
ounce - Afternoon Dose:
ounce
First, find a common denominator to add these fractions. The least common multiple of 8 and 7 is 56.
Convert each fraction to have a denominator of 56:
- For
:
= 
= 
- For
:
= 
= 
Add these fractions:
+ 
= 
So, the total amount of medication used is 
ounce.
The vial contains 1 ounce. The amount of medication remaining in the vial is:
1− 
= 
− 
= 
Since 
ounce is needed more to make up for the used amount, the nurse needs: 
of an ounce more.
Therefore, the correct answer is:
No, the nurse needs 
of an ounce more.
