To find the percentage decrease, you first calculate the difference between the original price and the new price. Then, divide that difference by the original price and multiply by 100 to express it as a percentage.

Formula: Percentage decrease = ((Original price - New price) / Original price) * 100

Substitute the given values: Percentage decrease = ((120 - 84) / 120) * 100 Percentage decrease = (36 / 120) * 100 Percentage decrease = 0.3 * 100 Percentage decrease = 30%

So, the percentage decrease is 30%.
