The price of an item yesterday was $180. Today, the price fell to $81. Find the percentage decrease
To find the percentage decrease, we need to calculate the difference between the initial price and the final price, and then divide that difference by the initial price:
Difference = Initial price - Final price
Difference = $180 - $81
Difference = $99
Now, divide the difference by the initial price:
Percentage decrease = (Difference / Initial price) * 100
Percentage decrease = ($99 / $180) * 100
Percentage decrease ≈ 55%
Therefore, the price of the item decreased by approximately 55%.
