Q: If a population of a town increases from 10,000 to 12,000 in a year, what is the percentage increase in population?

Solution: Increase = 12000 - 10000 = 2000; Percentage increase = (2000/10000) * 100 = 20%.

Steps: 8

Step 1: Identify the initial population, which is 10,000.
Step 2: Identify the new population, which is 12,000.
Step 3: Calculate the increase in population by subtracting the initial population from the new population: 12,000 - 10,000.
Step 4: The result of the subtraction is 2,000, which is the increase in population.
Step 5: To find the percentage increase, divide the increase (2,000) by the initial population (10,000).
Step 6: The result of the division is 0.2.
Step 7: To convert the decimal to a percentage, multiply by 100: 0.2 * 100.
Step 8: The final result is 20%, which is the percentage increase in population.
