What score did Ken need for his 6th grade to maintain a 92% average in English?

To determine the score Ken needs in order to maintain a 92% average in English after six grades, it’s necessary to first calculate the total points he would need across all six grades.

If Ken wants an average of 92% after six grades, the total percentage points he needs is calculated as follows:

1. Multiply the desired average (92%) by the total number of grades (6). This gives 92 * 6 = 552 total points needed.
2. Next, add up Ken's scores from the first five grades. Let's assume he has earned a certain total (let's say he has grades of 90, 92, 93, 91, and 88, which might total to 454 points, though the exact scores aren't specified in the question).

After calculating the sum of the first five grades, you'd subtract this from the total points needed (552) to find out what score he needs on the sixth grade. Therefore, if his total from the first five grades summed up to 454 points, then:

552 (required total) - 454 (earned total) = 98.

In terms of maintaining a 92% average, if Ken were to score 97 on the sixth test
