Questions & Step-by-Step Solutions

If a number is increased by 20% and then decreased by 20%, what is the net change in the number?
  • Step 1: Start with a number. Let's use 100 as an example.
  • Step 2: Calculate 20% of 100. 20% of 100 is 20.
  • Step 3: Increase the number by 20. So, 100 + 20 = 120.
  • Step 4: Now, calculate 20% of the new number, which is 120. 20% of 120 is 24.
  • Step 5: Decrease the new number (120) by 24. So, 120 - 24 = 96.
  • Step 6: Find the net change from the original number (100) to the final number (96).
  • Step 7: Calculate the change: 96 - 100 = -4.
  • Step 8: To find the percentage change, divide the change by the original number and multiply by 100: (-4 / 100) * 100% = -4%.
