Final answer:
The original price of $150 for the dress that Maria saw in the boutique represents the asking price, which is the initial price set by the seller before negotiation.
Step-by-step explanation:
The asking price is the price that a seller states they are willing to accept for an item they are selling. In the situation described, the $150 represents the asking price. Maria spotted a beautiful dress in the window of a boutique with a price of $150, which is the price the boutique was asking for the dress before any negotiation. After negotiation, Maria and the salesperson agreed on a price of $125 for the dress, which is lower than the original asking price but higher than Maria's initial offer.
