A(AN) can be used like the word "per".

Examples:

• Apples currently cost $1.30 a pound.
• Cheetahs can run 60 miles an hour.
• You want $150 a person for the tour?

If a direction (north, west, southeast, left, right) directly follows a verb, do not use an article with the direction.

Examples:

• We need to walk south.
• They drove north all day.
• At the stop sign, turn left and walk three blocks.

HOWEVER: If a direction follows a preposition, you must use THE.

Examples:

• We need to walk to the south.
• Our house is in the north.
• The grocery store is on the right.

MOREOVER: Use THE with compass directions when referring to them as special geographic or cultural regions.

Examples:

• We love the South.
• Have you ever visited the East?
• The West has better national parks.
