Questions & Step-by-Step Solutions

If a population of a town increases from 10,000 to 12,000 in a year, what is the percentage increase in population?
Correct Answer: 20%
  • 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.
