An environmental charity is organizing a community garden planting event.
The table below shows the quantity of supplies needed for each volunteer adult and each junior helper attending the event.
| Supply | Adult | Junior |
|---|---|---|
| Seed Compost | 4.5 litres | 1.5 litres |
| Biodegradable Pots | 12 pots | 4 pots |
| Sapling Stakes | 3.0 stakes | 1.0 stake |
An algorithm is used to determine how much seed compost, how many biodegradable pots, and how many sapling stakes to order for an event based on attendance numbers.

Write Python code to implement the algorithm shown in the flowchart.
