The statement is incomplete as written — I need one more piece of information to get a unique answer (for example, the fixed part or a second cost for a different time).
Explanation and quick options:
- If 850 is the cost for 4 hours and the cost is purely proportional to time (no fixed charge), then 12 hours costs 3 × 850 = 2,550.
- If there is a fixed charge a plus an hourly rate r, and 850 = a + 4r, then the 12‑hour cost is a + 12r = 850 + 8r. That cannot be evaluated without knowing r (or a).
Please confirm exactly what “#850 for 4 …” means (4 hours or 4 lorries?), and whether there is any other given cost so I can compute the 12‑hour charge.
