Final answer:
The pair of jeans is on sale at a 34.21% decrease in price.
Step-by-step explanation:
To calculate the percent decrease in price, we can use the formula:
Percent decrease = [(original price - new price)/original price] x 100
In this case, the original price is $38 and the new price is $25.
So, the percent decrease in price is:
[(38 - 25)/38] x 100 = 13/38 x 100 = 34.21%
Therefore, the pair of jeans is on sale at a 34.21% decrease in price.
