Use 4 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 20 score 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 youth center and check the inventory.

Count the 80 score cards before visitors arrive. Confirm a clear entrance and an accessible work area at the youth center, then give each of the 4 group leads the same timing sheet.

Supplies: 80 × $5.05 = $404.00. Reserve: $404.00 × 0.10 = $40.40. Planned total: $444.40. This is a planning calculation using the supplied prices.

Remove 20 units, leaving 60. Supplies become $303.00; a 10% reserve adds $30.30, for a total of $333.30.

```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: score cards,80 ```

The row `score cards,80` should pass. The row `score cards,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Youth Chess Club Location: youth center; day: Monday. Inventory: 80 score cards, allocated as 4 groups × 20. 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 20 score 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 score 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 score cards before checking the group capacity. Keep the reply specific to the youth center session and offer a clear next step: speak with the welcome desk.
