To solve the problem we must know about Percentage.

Percentage

A percentage is a way to describe a part of a whole. such as the fraction [tex]\bold{\dfrac{1}{4}}[/tex] can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given to us

  • A sweater is marked down $25 to $19

Assumption

Let the x% be the remaining amount.

Remaining Amount

x% of $25 = $19

[tex]\dfrac{x}{100} \times \$25 = \$19\\\\\dfrac{x}{100} \times 25 = 19\\\\\dfrac{x}{4} = 19\\\\x = 19\times 4\\x = 76[/tex]

Thus, $19 is 76% of $25.

Percent of change

the percent of change =  Orignal percentage - final percentage

                                      =  100% - 76%

                                      =  24%

Hence, the percentage change is 24%.
