In 2013, there were 250 students at Highmoor Sixth Form.
In 2014, there were 280 students.
Work out the percentage increase from 2013 to 2014.
To calculate the percentage increase from 2013 to 2014, we need to find the difference in the number of students between the two years and express it as a percentage of the starting number of students in 2013.
The difference in the number of students between 2013 and 2014 is 280 - 250 = 30 students.
To express this as a percentage of the starting number of students in 2013, we divide the difference by the starting number and multiply by 100:
(30 / 250) * 100 = 0.12 * 100 = 12%
Therefore, the percentage increase from 2013 to 2014 is 12%.
