Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_98 (roll VARCHAR, area VARCHAR, decile VARCHAR, authority VARCHAR)

### Question ###
What is the total roll with a decile less than 7, and an authority of state, in the Macraes Flat area?

SELECT COUNT(roll) FROM table_name_98 WHERE decile = 7 AND authority = "state" AND area = "macraes flat"
