Answer:
127
Step-by-step explanation:
Given that a company delivers newspaper to the town of wayland. It has 158 customer on the north side of town, 378 customers on the west side, 237 customers on the south side
It does not depend on the side of the town
For the total town the total number of customer's = number of customer's is north side + the number of customer's in west side + number of customer's in south side
Total number of customer's = 158 + 378 + 237 = 773
Given that the company received a total number of 900 newspaper's
The number of newspaper left over = total number of newspaper's received - total number of customer's = 900-773 = 127
Therefore the total number of newspaper left over are 127
