1 answer

To find the total mail delivered for December and January, you need to add the mail delivered in each month.

Total mail delivered = 7.14 x 10^10 + 3.21 x 10^10

Total mail delivered = 10.35 x 10^10

Total mail delivered = 1.035 x 10^11

Therefore, the total mail delivered for December and January is 1.035 x 10^11 pieces.
