Question
The price of an item has dropped to 140. Find the percentage decrease.
Solution
Sure, here are the steps to find the percentage decrease:
-
First, find the difference in price from yesterday to today. This is done by subtracting the new price from the old price. So, 42 = $98. This is the amount the price has decreased.
-
Next, to find the percentage decrease, divide the decrease by the original price (the price from yesterday). So, 140 = 0.7.
-
Finally, to convert this number into a percentage, multiply by 100. So, 0.7 * 100 = 70%.
Therefore, the price of the item has decreased by 70%.
