Answer 1

To find the percent decrease, calculate the difference in the number of students between last year and this year, and then calculate the percent decrease.

Step-by-step explanation:

To find the percent decrease in the number of students, we need to calculate the difference in the number of students between last year and this year.

Step 1: Calculate the difference in the number of students: 525 - 420 = 105.

Step 2: Calculate the percent decrease: (105 / 525) * 100 = 20%.

Therefore, the percent of decrease is 20%.
