Questions & Step-by-Step Solutions

If a population of a town increases by 15% in one year, what will be the population after one year if the current population is 20,000?
Correct Answer: 23,000
  • Step 1: Identify the current population of the town, which is 20,000.
  • Step 2: Calculate 15% of the current population. To do this, multiply 20,000 by 0.15 (which is 15% in decimal form).
  • Step 3: Perform the multiplication: 20,000 * 0.15 = 3,000. This is the increase in population.
  • Step 4: Add the increase to the current population. So, 20,000 + 3,000 = 23,000.
  • Step 5: The new population after one year will be 23,000.
