Question

the high school graduating class of 200 had 260 students. five years later, the graduating class was 400 students. by 2010, the graduating class rose 525 students. in what five year period did the graduating class experience the greatest percent of change

Answer 1

The five-year period where the class went from 260 to 400 saw the greatest change in terms of percentage.

Explanation:

To calculate the change in percentage we subtract the old number from the new number then divide it by the old number.

400 - 260 = 140

140 ÷ 260 = 0.5385 or 53.85%

525 - 400 = 125

125 ÷ 400 = 0.3125 or 31.25%

Since 53.85% is greater than 31.25%, that means the period where it from 260 to 400 saw the greatest change.
