Answer:
The least score the student can get is 71 to get an overall B average at the end of the year.
Step-by-step explanation:
Let the score she needs to get be = x
We now have to take the mean of all the five subjects <em>(including x)</em> and equate it to the least score she can have to get a B grade.
Let us take the least score the student needs to get a B grade to be 85
Mean of all 5 scores =
![\frac{95+83+91+85+x}{5}=85](https://tex.z-dn.net/?f=%5Cfrac%7B95%2B83%2B91%2B85%2Bx%7D%7B5%7D%3D85)
![\frac{354+x}{5} =85](https://tex.z-dn.net/?f=%5Cfrac%7B354%2Bx%7D%7B5%7D%20%3D85)
![354+x = 425](https://tex.z-dn.net/?f=354%2Bx%20%3D%20425)
![x = 71](https://tex.z-dn.net/?f=x%20%3D%2071)
The least score the student can get is 71 to get an overall B average at the end of the year.
