To find the percent increase of Oliver's grade, we need to calculate the difference between his old grade and his new grade, and then divide that difference by his old grade.
The difference between his old grade (85) and his new grade (92) is 92 - 85 = 7.
Now, divide the difference by his old grade: 7 / 85 = 0.08235.
Finally, multiply the result by 100 to convert it to a percentage: 0.08235 * 100 = 8.235.
The percent increase of Oliver's grade is approximately 8.235%. Therefore, the correct answer is D.
