On a biology test, a student got 25 questions correct but did not pass. On a second attempt, the student got 32 questions correct. What was the percent of increase?
32 - 25 = 7
7/25 = 0.28 = 28%
Thank you!
You're welcome.
To calculate the percent increase, you need to find the difference between the two values and then express it as a percentage of the original value.
First, let's calculate the difference between the two values:
32 (questions correct on the second attempt) - 25 (questions correct on the first attempt) = 7
Next, we need to find the percent increase from the original value (25) to the final value (32). To do this, divide the difference by the original value and multiply by 100:
(7 / 25) * 100 = 28%
Therefore, the percent of increase in the number of questions correctly answered from the first attempt to the second attempt is 28%.
