Question

On a biology test, a student got 25 questions correct but did not pass. On a second attempt, the student got 37 questions correct. What was the percent of increase?

Answer 1

The percent of increase is 32.43%.

Explanation:

Take the difference of his new score and the old score.

37-25 = 12

To find the percent change, take that difference and divide it by the new score. Then multiply that answer by 100%.

12/37 = .3243

.3243 x 100% = 32.43%
