Can be used to compare changes from one period to another.

vlada-n [284]

Answer:

c) Percentages

Step-by-step explanation:

Percentages can be used to compare changes from one period to another.

In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.

For example, let's find percentage increase of the number of students that joined a book club using the parameters below;

Original number of students = 32

New number of students = 36

We will calculate the increase using;

$Increase = original \; number - new \; number$

Substituting the values, we have;

Increase = 36 - 32 = 4

$Percentage \; increase = \frac{increase}{original \; number} * 100$

$Percentage \; increase = \frac{4}{32} * 100$

$Percentage \; increase = 0.125 * 100$

Percentage increase = 12.5%

Therefore, the number of students in the school club increased by 12.5%.
