Find each percent increase. Round to the nearest percent. From 24 teachers to 30

DedPeter [7]

The percent increase is 25 %

Solution:

Given that we have to find the percent incraese

From 24 teachers to 30

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

The percent increase is given as:

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

Here, initial value = 24 and final value = 30

Substituting the values in above formula, we get

$Perecnt\ Increase = \frac{30-24}{24} \times 100\\\\Perecnt\ Increase = \frac{6}{24} \times 100\\\\Perecnt\ Increase = 0.25 \times 100\\\\Perecnt\ Increase = 25$

Thus percent increase is 25 %
