There's a parking lot that is 600m² big. The lot must be able to hold at least 3 buses and 10 cars.
Each car takes up 6m² and each bus takes up 30m².
However, there can only be 60 vehicles in the lot at any given time.
The cost to park in the lot is $2.50 per day for cars and $7.50 per day for buses. The lot must make at least $75 each day to break even.
What is a possible car to bus ratio that would allow the lot to make profit?

Answer:
a blog
Explanation:
a forum is for questions, a wiki doesn't make sense in this situation and email wouldn't be used for this either so it should be a blog
Answer:
Following are the code to this question:
/*using the select statement, that selects column name from the table blog.posts */
SELECT blog.posts.user_id, blog.posts.body, users.name/*column name user_id, body, name*/
FROM blog.posts/* use table name blog.posts*/
RIGHT OUTER JOIN users ON blog.posts.user_id = users.id;/*use right join that connect table through user_id*/
Explanation:
In the structured query language, RIGHT JOIN is used to recovers from both the right side of the table both numbers, although the left table has no sets. It also ensures that even if the 0 (null) documents are linked inside this left table, its entry will always return the outcome row, but still, the number of columns from its left table will be NULL.
In the above-given right join code, the select statements used that selects the column names "user_id, body, and the name" from the table "blog. posts" and use the right join syntax to connect the table through the id.
