🔟 PRIZE MONEY — CLEAR EXAMPLES
Each participant puts:

+ 200 MXN administrative fee (non-refundable)
But the prize pool is only from 3,000 MXN cash entries.
💰 EXAMPLE 1 — 10 participants
10 × 3,000 = 30,000 MXN total prize
If 5 people succeed:
➡️ 30,000 / 5 = 6,000 MXN per winner
= they double their money
💰 EXAMPLE 2 — 20 participants
20 × 3,000 = 60,000 MXN
If 8 succeed:
➡️ 60,000 / 8 = 7,500 MXN per winner
💰 EXAMPLE 3 — 30 participants
30 × 3,000 = 90,000 MXN
If only 6 succeed:
➡️ 90,000 / 6 = 15,000 MXN per winner
