Oliver raised his grade from an 85 to a 92 for the semester. What was the percent increase of his grade?

Answer 1

To find the percent increase, we first need to find the difference between the two grades: 92 - 85 = <<92-85=7>>7.
Then, we divide this difference by the original grade and multiply by 100%: (7 / 85) * 100% = 0.08 * 100% = 8%. Answer: \boxed{8}.
