Answer:

Option C

Step-by-step explanation:

Given that:

George has a goal to make an average of 90% for the first grading period. There will be 10 grades averaged together to determine the grade for the grading period.

The first 9 grades scores were

92, 86, 90, 79, 98, 75, 89, 98, 97

Total of these 9 grades =804

He wants to get 90% average

This is equivalent to getting 900 as total for all 10 grades

Hence atleast he should get 900-804 = 96 score to make an average of 90%

Answer is option C
