Explanation:
Given: Number of students who were given Cardinal Credits last week for good behavior = 14
Number of students who were given Cardinal Credits this week for good behavior = 22
To find: percent increase in number of students who were given Cardinal Credits
Solution:
Increase in number of students = 22 - 14 = 8
Percent increase in number of students who were given Cardinal Credits = Increase in number of students / Number of students who were given Cardinal Credits last week for good behavior × 100
![=(8)/(14)* 100=57.14\approx 57\%](https://img.qammunity.org/2021/formulas/mathematics/high-school/y33haz8sjjw2ymhgvuvutrffxpqxnx8y84.png)
