Question

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

Answer 1

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{ = }(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%.
