Answer:
B. 7.3 %
Step-by-step explanation:
Given:
Initial average grade = 82
Final average grade = 88
Duration for the increase = 3 weeks
Therefore, increase in average grade = Final - Initial = 88 - 82 = 6
Now, percent increase in average grade is given as:
![\% \textrm{increase}=\frac{\textrm{Increase}}{\textrm{Initial grade}}\times 100\\\% \textrm{increase}=\frac{6}{82}\times 100\\\% \textrm{increase}=\frac{600}{82}=7.3\%](https://tex.z-dn.net/?f=%5C%25%20%5Ctextrm%7Bincrease%7D%3D%5Cfrac%7B%5Ctextrm%7BIncrease%7D%7D%7B%5Ctextrm%7BInitial%20grade%7D%7D%5Ctimes%20100%5C%5C%5C%25%20%5Ctextrm%7Bincrease%7D%3D%5Cfrac%7B6%7D%7B82%7D%5Ctimes%20100%5C%5C%5C%25%20%5Ctextrm%7Bincrease%7D%3D%5Cfrac%7B600%7D%7B82%7D%3D7.3%5C%25)
Therefore, the percent increase in her average grade over the 3-week period is 7.3 %.
