If the price of a shirt is increased by 20% and then decreased by 20%, what is the net change in the price of the shirt?
Step 1: Assume the original price of the shirt is 100.
Step 2: Calculate the price after a 20% increase. 20% of 100 is 20, so the new price is 100 + 20 = 120.
Step 3: Calculate the price after a 20% decrease from the new price of 120. 20% of 120 is 24, so the new price is 120 - 24 = 96.
Step 4: Find the net change in price. The original price was 100, and the final price is 96.
Step 5: Calculate the net change percentage using the formula: (final price - original price) / original price * 100%. So, (96 - 100) / 100 * 100% = -4%.
