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 (including x) 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 =
[tex]\frac{95+83+91+85+x}{5}=85[/tex]
[tex]\frac{354+x}{5} =85[/tex]
[tex]354+x = 425[/tex]
[tex]x = 71[/tex]
The least score the student can get is 71 to get an overall B average at the end of the year.
