Answer:
no change
Step-by-step explanation:
Let the sticker price = x
Price reduced by $300
Hence the new price = x-$300
The cost of additional features = $900
Hence the new price fo selling will be x-$300+$900
=x+$600
now Dealer also provide a discount of $600
Hence Final selling price will be
=x+$600-$600
=x
Hence thee seems to be no change in the sticker price as the sticker price and the final selling price are the same.
