To find the percent discount on Teena's favorite jeans, you need to calculate the difference between the original price and the sale price, and then express that difference as a percentage of the original price.

Step 1: Find the difference between the original price and the sale price.
The original price is $30, and the sale price is $25. So, the difference is $30 - $25 = $5.

Step 2: Express the difference as a percentage of the original price.
To find the percentage, divide the difference by the original price and multiply by 100: ($5 / $30) * 100.

Performing the division: $5 / $30 = 0.1667.

Multiplying the result by 100: 0.1667 * 100 = 16.67.

Therefore, the percent discount on Teena's favorite jeans is approximately 16.67%.
