Q: A population of a town increased from 20,000 to 25,000 in a year. What is the percentage increase in population?

Solution: Percentage increase = ((25000 - 20000) / 20000) * 100 = 25%.

Steps: 8

Step 1: Identify the initial population, which is 20,000.
Step 2: Identify the new population, which is 25,000.
Step 3: Calculate the increase in population by subtracting the initial population from the new population: 25,000 - 20,000.
Step 4: The result of the subtraction is 5,000, which is the increase in population.
Step 5: To find the percentage increase, divide the increase (5,000) by the initial population (20,000): 5,000 / 20,000.
Step 6: The result of the division is 0.25.
Step 7: To convert the decimal to a percentage, multiply by 100: 0.25 * 100.
Step 8: The final result is 25%, which is the percentage increase in population.
