Fittoniya [83]

The percent of change in student enrollment is 1.81 % increase

<em><u>Solution:</u></em>

Given that, The number of students who attended FPM in 2015 was 1380

In 2016, 1405 students attended FPM

To find: Percent change

<em><u>The percent change is given by formula:</u></em>

\text { percent change }=\frac{\text { final value - initial value}}{\text { initial value }} \times 100

If the result is positive, it is percent increase

If the result is negative, it is percent decrease

From given,

Initial value in 2015 = 1380

Final value in 2016 = 1405

<em><u>Substituting the values in formula, we get</u></em>

<em><u></u></em>\text { percent change }=\frac{1405-1380}{1380} \times 100\\\\\text { percent change }=\frac{25}{1380} \times 100\\\\\text { percent change }= 0.01811 \times 100\\\\\text { percent change }= 1.81<em><u></u></em>

Thus percent of change in student enrollment is 1.81 % increase

Answer:

7 < x < 17

Step-by-step explanation:

Solving the first equation:

x + 5 > 12

x > 7 (subtract 5 from both sides)

Solving the second equation:

x - 5 < 12

x < 17 (add 5 to both sides)

Now, combine the two equations:

x > 7 and x < 17 become

7 < x < 17
