When A Tuba Is Played, The Player Makes A Buzzing Sound And Blows Into One End Of A Tube That Has An

If the population of Placerville grew from 4740 a decade ago to 7040 today. Then, the Absolute change = 2300 and percentage change = 48.5 %, which implies that option C is the right choice for this question.

The rate of change between two quantities is given by –

rate of change = new value – old value

The rate of change can be positive or negative.

The rate of change is also called Absolute change.

% of change = (absolute change / old value) x 100

Here, we are given that the population grew from 4740 a decade ago to 7040 today.

hence, we have the old value = 4740 and the new value = 7040.

now let us find the absolute change using the above formula –

Absolute change = new value – old value

Absolute change = 7040 – 4740

Absolute change = 2300

Now, let us find the percentage change using the above formula as follows –

% of change = (absolute change / old value) x 100

% of change = (2300 / 4740) x 100

% of change = 0.485 x 100

% of change = 48.5 %

Hence, we get Absolute change = 2300 and % of change = 48.5 %, which implies that option C is the correct choice for this question.
