Use the 4 Step Plan and turn in on Friday, October 2nd

The basic format for a correct answer in the P.O.W. 4 Step Plan is below:

SEE:
What is the question asking? Restate in your own words.
What do I know? List all important facts from the question (or circle/highlight on the printed question and underline the question)

PLAN:
Because you know how many total pieces of mail were sent (10) and you know how

DO: Show your work and Box your answer

CHECK:
