Consumer surplus can be defined as the amount that the consumer is willing to pay for a product or a service. The word surplus is a synonym for something extra or excess. It corresponds to the extra benefit that the consumer gets while buying something which may be the result of some discount, sale, or negotiation.
Jeff realizes a consumer surplus of $700 while purchasing a laptop of $3000. As the consumer surplus is $700,
the amount Jeff has paid for the laptop is: $3000 - $700

Answer:
The SQL query is used to create a copy of a table like the 1_employee table in the SQL database.
Explanation:
create table copy_of_employees as select EMPLOYEE_ID, FIRST_NAME, LAST_NAME, DEPT_CODE, HIRE_DATE, CREDIT_LIMIT, PHONE_NUMBER, MANAGER_ID from l_employees;
INSERT INTO copy_of_employees SELECT * FROM l_employees;
SELECT * FROM copy_of_employees;
This SQL creates a table called copy_of_employees and copies the selected query of the 1_employees table and inserts it to the newly created table.
