Answer:
the new selling price of the house is $390,450.
Explanation:
If the Palermo's originally listed their house for $411,000 and they decided to mark the price down by 5%, the new selling price of their home is $411,000 - (5/100 * $411,000) = $411,000 - $20,550 = $<<411000-(5/100*411000)=390450>>390,450.
The original price of the house was $411,000, and the price was marked down by 5%, which is equivalent to 5/100 * $411,000 = $20,550. When this amount is subtracted from the original price, the new selling price of the house is $390,450.
