Questions & Step-by-Step Solutions
A population of a town increased from 10,000 to 12,500. What is the percentage increase?
Step 1: Identify the initial population, which is 10,000.
Step 2: Identify the new population, which is 12,500.
Step 3: Calculate the increase in population by subtracting the initial population from the new population: 12,500 - 10,000.
Step 4: The result of the subtraction is 2,500, which is the increase in population.
Step 5: To find the percentage increase, divide the increase (2,500) by the initial population (10,000): 2,500 / 10,000.
Step 6: The result of the division is 0.25.
Step 7: To convert this to a percentage, multiply by 100: 0.25 * 100.
Step 8: The final result is 25%, which is the percentage increase in the population.
Percentage Increase – The percentage increase is calculated by taking the difference between the new value and the original value, dividing it by the original value, and then multiplying by 100.
