Answer: To find the percent of change from seventh grade to eighth grade, we can use the formula:
percent change = (new value - old value) / old value * 100%
where "old value" is the value in seventh grade and "new value" is the value in eighth grade.
In this case, the old value is 96 and the new value is 91. Substituting into the formula, we get:
percent change = (91 - 96) / 96 * 100%
Simplifying, we get:
percent change = -5.21%
Therefore, the percent of change in Vera's final average from seventh grade to eighth grade is approximately 5.21% decrease.
