If Jaylen used a 20% discount on a pair of jeans that cost $70 before tax, then the price of the jeans will be $70 - 20%.
Let's calculate the 20% of $70.
![70*20\%=14](https://img.qammunity.org/2023/formulas/mathematics/college/hmb2nyp42zn8xog82hefjzcgrdx18wik1l.png)
So, the discounted price of the jeans before tax is $70 - $14 = $56.
Generally, sales tax is applied to the discounted price, so let's calculate the 6% of $56.
![6\%*56=3.36](https://img.qammunity.org/2023/formulas/mathematics/college/dgns1v9674himhii1h6wobutkitq3ydupi.png)
The sales tax is $3.36.
Therefore, the cost of the pair of jeans after tax is $59.36.
