What does Patina observe about house numbers on the drive to MLK Park?

As Momly drives Patina to MLK Park, they pass large, fancy houses. Those houses always have one or two numbers for their address, like 6 Chester Avenue or 13 Chester Place. In older neighborhoods where Patina lives with Momly and Uncle Tony, the addresses have three numbers, like 685 Wallery Street. Patina's mother's address has four--5014. Patina thinks that Ghost's address has five or six numbers. She decides it is like the fewer numbers in "your bank account, the more numbers in your address" (96).
