Question

A town’s population went from 35,000 to 42,000 in 3 years. What was the percent of change?

Answer 1

Answer:

The population changed by 20% in 3 years

Step-by-step explanation:

The percentage change, is given by the following equation;

$Percentage \ change = \dfrac{Final \ value - Initial \value }{Initial \ value} \times 100$

The given parameters are;

The initial population of the town = 35,000

The final population of the town = 42,000

The percentage change in the population is therefore;

$Percentage \ change \ in \ population= \dfrac{42,000 - 35,000 }{35,000} \times 100 = 20 \%$

The population changed (increase) by 20% in 3 years.
