Use 4 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 15 song sheets to each group. 00:20–01:05: run the main activity. 01:05–01:20: collect feedback and reusable equipment. 01:20–01:30: clean the music room and check the inventory.

Count the 60 song sheets before visitors arrive. Confirm a clear entrance and an accessible work area at the music room, then give each of the 4 group leads the same timing sheet.

Supplies: 60 × $4.70 = $282.00. Reserve: $282.00 × 0.10 = $28.20. Planned total: $310.20. This is a planning calculation using the supplied prices.

Remove 15 units, leaving 45. Supplies become $211.50; a 10% reserve adds $21.15, for a total of $232.65.

Join Community Choir this Tuesday at the music room. Meet neighbors, learn together, and take part at your own pace. We will share the available song sheets across small groups. Supplies are limited, so please check with the welcome desk when you arrive.

Community Choir Tuesday · music room Welcome! Ask the desk about available song sheets and today’s small-group activities.

```python import csv def read_inventory(path): rows = [] with open(path, newline="", encoding="utf-8") as handle: reader = csv.DictReader(handle) if reader.fieldnames != ["item", "quantity"]: raise ValueError("Expected item,quantity columns") for line, row in enumerate(reader, 2): name = row["item"].strip() quantity = row["quantity"].strip() if not name or not quantity.isascii() or not quantity.isdecimal(): raise ValueError(f"Invalid inventory row {line}") rows.append((name, int(quantity))) return rows # Example row: song sheets,60 ```

The row `song sheets,60` should pass. The row `song sheets,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Community Choir Location: music room; day: Tuesday. Inventory: 60 song sheets, allocated as 4 groups × 15. Before opening: count supplies, set the welcome desk, and confirm group leads. During the event: record shortages and visitor questions. After closing: count returns and write one improvement for the next meeting.

Ask: “Were 15 song sheets per group enough for the activity, and which step created the longest wait?” Record the answer beside the returned inventory count.

You are welcome to check in at the desk when you arrive. A coordinator can explain the current activity and see whether a group has space and spare song sheets. If the activity is already full, we can help you observe or find the next joining point.

Avoid guaranteeing a place or a set of song sheets before checking the group capacity. Keep the reply specific to the music room session and offer a clear next step: speak with the welcome desk.
