The price of an item has dropped to $63 today. Yesterday it was $140. What was the percentage decrease?

den301095 [7]

Given:

a.) The price of an item has dropped to $63 today.

b.) Yesterday it was $140.

For us to be able to determine the percentage decrease, we will be using the following formula:

$\text{ Percentage Decrease = }\frac{\text{ Original Price - Present Price}}{\text{ Original Price}}\text{ x 100}$

We get,

Original Price = $140

Present Price = $63

$\text{ Percentage Decrease = }\frac{\text{ Original Price - Present Price}}{\text{ Original Price}}\text{ x 100}$ $\text{ = }\frac{\text{ 140 - 63}}{\text{ 140}}\text{ X 100}$ $\text{ = }\frac{77}{140}\text{ X 100}$ $\text{ = }0.55\text{ x 100}$ $\text{Percentage Decrease = }55\text{\%}$

Therefore, the decrease of the price in percentage is 55%.
