Question

Describe how to find the rate of increase if the population of a town changes from 47,230 to 55,112 people. Then calculate the amount of change.

Answer 1

Answer:

The rate of change of population is 16.69%.

Step-by-step explanation:

Rate of increase is defined as the ratio of difference of quantity increased by the original quantity multiplied by 100

that is $\text{Rate}=\dfrac{\text{Increased quantity - original quantity}}{\text{Original quantity}} \times 100$   ...........(1)

To find the rate of increased population of t town from 47,230 to 55,112

Here, original population = 47,230

Increased population = 55,112

Put the values in (1),

$\text{Rate}=\dfrac{55112-47230}{47230} \times 100$

$\text{Rate}=\dfrac{7882}{47230} \times 100$

$\text{Rate}=16.69$(approx)

Thus, the rate of change of population is 16.69%.
