Instruction
For the purpose of the short quiz, we'll introduce another table: advertisement.
Exercise
Select all the information from the advertisement table.
The owner of the websites decided to try another business model: now, there is a single advertisement on the websites and an auction takes place. Whoever pays the highest price, gets their ad on the websites for a single day. The table is very simple: it only shows how much was paid (price) after the auction on a given date (day).
