To find the sale price before sales tax, you can follow these steps:

1. Calculate the discount: Multiply the original price by the discount percentage. In this case, the discount is 40% of $50, so the discount is (40/100) x $50 = $20.

2. Subtract the discount from the original price: Subtract the discount amount from the original price to get the sale price. In this case, the sale price before sales tax is $50 - $20 = $30.

Therefore, the sale price of the pen before sales tax is $30.
