Answer:

Percent change = 5.4%

Step-by-step explanation:

Given:

Number of students voted last year = 762

Number of students voted this year = 721

Change in the number of students who voted from last year to this year is given by the difference of their number. This gives,

Change in the number of students that voted = 762 - 721 = 41

Now, percentage change in the number of students that voted is given as:

$\textrm{Pecent change}=\frac{\textrm{Change in number}}{\textrm{Number last year}}\times 100\\\\\textrm{Pecent change}=\frac{41}{762}\times 100\\\\\textrm{Pecent change}=\frac{4100}{762}=5.38\%\approx 5.4\%$

Therefore, the percent change in the number of students that voted is 5.4%.
