Question

Last year 762 students voted in the student council election at San Bruno Middle School this year 721 students voted to the nearest tenth what was the percent of change in the number of students that voted

Answer 1

Percent change = 5.4%

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}}* 100\\\\\textrm{Pecent change}=(41)/(762)* 100\\\\\textrm{Pecent change}=(4100)/(762)=5.38\%\approx 5.4\%`

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