QA found yesterday that the export drops the timezone on some dates, so we will not ship on Tuesday as planned. We now plan to ship on Thursday, provided Leon reviews Mira's fix by noon Wednesday and QA verifies it by 5 p.m. Wednesday. Please inform support of the change today.

**Calculation:**

1. Initial bookings: 3/5 × 240 = **144** seats
2. After changes: 144 − 18 + 37 = **163** attendee bookings
3. Seats taken in total: 163 attendees + 12 crew = **175**
4. Seats still available: 240 − 175 = **65**

Answer: 65 seats

Final answer: 65 seats · Correct on this problem

* Initial bookings: $\frac{3}{5} \times 240 = 144$ seats
* Updated attendee bookings: $144 - 18 + 37 = 163$ seats
* Total unavailable seats (attendees + crew): $163 + 12 = 175$ seats
* Available seats: $240 - 175 = 65$ seats

A database table is like a huge spreadsheet. Say you want every order from the customer "Acme." Normally the database reads every row from top to bottom, like scrolling through a million-row sheet looking for matches.

An index is a separate, sorted lookup list, like the index at the back of a book. An index on the CustomerName column lists each name alphabetically, with pointers to the exact rows where it appears. The database can jump straight to "Acme" and grab only those rows, turning a slow, full-table search into a near-instant lookup.

The cost is that every time a row is added, changed, or deleted, the database must also update the index to keep it sorted. Indexes make reading faster but writing slower. That's why you index the columns people search often, not every column.

Imagine a massive spreadsheet of 100,000 customer orders sorted by Order Date. If you need to find every order for "Customer X," you have to scan every single row from top to bottom. In a database, this is a slow "full table scan."

A database index solves this. It works like a hidden, second tab in your spreadsheet that lists only Customer Names alphabetically, right next to the exact row numbers where their orders live in the main tab. When you search for "Customer X," the database checks this alphabetical index, grabs the row numbers, and jumps straight to the data instantly. 

However, indexes have a cost: they slow down data entry. Every time you add, delete, or edit an order in your main table, the database must also take time to update and re-sort that hidden index tab, while also using extra storage space.
