Final answer:
There will be 168 newspapers delivered in the Silver Hills neighborhood in December.
Step-by-step explanation:
Let's first calculate the total number of houses in the Silver Hills neighborhood:
Total houses per street = 16 houses
Total streets in the neighborhood = 12 streets
Total houses in the neighborhood = Total houses per street * Total streets
= 16 houses/street * 12 streets
= 192 houses
Now, the newspaper company reported a 1/8 drop in homes purchasing newspapers. This means that 1 - 1/8 = 7/8 of the houses will still purchase newspapers.
So, the number of houses purchasing newspapers in December = (7/8) * Total houses
= (7/8) * 192 houses
= 168 houses
Therefore, the newspaper company will deliver newspapers to 168 houses in the Silver Hills neighborhood in December.
