Use 3 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 16 practice cards 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 dance room and check the inventory.

Count the 48 practice cards before visitors arrive. Confirm a clear entrance and an accessible work area at the dance room, then give each of the 3 group leads the same timing sheet.

Supplies: 48 × $11.00 = $528.00. Reserve: $528.00 × 0.10 = $52.80. Planned total: $580.80. This is a planning calculation using the supplied prices.

Remove 16 units, leaving 32. Supplies become $352.00; a 10% reserve adds $35.20, for a total of $387.20.

Join Dance Practice Collective this Thursday at the dance room. Meet neighbors, learn together, and take part at your own pace. We will share the available practice cards across small groups. Supplies are limited, so please check with the welcome desk when you arrive.

Dance Practice Collective Thursday · dance room Welcome! Ask the desk about available practice cards 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: practice cards,48 ```

The row `practice cards,48` should pass. The row `practice cards,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Dance Practice Collective Location: dance room; day: Thursday. Inventory: 48 practice cards, allocated as 3 groups × 16. 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 16 practice cards 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 practice cards. 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 practice cards before checking the group capacity. Keep the reply specific to the dance room session and offer a clear next step: speak with the welcome desk.
