Lanee purchased a briefcase online. The total bill of $95.68 included a $5.25 shipping charge and 5% tax on the purchase. If Lanee used a $5 off promotional code that was applied before tax, how much was the original price of the briefcase?

Price plus tax = Total amount - Shipping charge

Price plus tax = $95.68 - $5.25

Price plus tax = $90.43

Let, x is the price excluding tax :

Also, she used $5 off promo code.

So, Original price = $86.12 + $5

Original price = $91.12 .

Hence, this is the required solution.
