ADD TimeAdded DATETIME

Explanation:

ALTER TABLE is the alter table statement with the name of the table being altered as the Products table. Then you ADD the column's name you're adding, which is a decimal with 5 points of precision, 3 to the left of the decimal and 2 to the left, represented by DECIMAL(5,2) and a default value of 9.99. Lastly, the TimeAdded that a product was added can be simply a DATETIME typed column.
