The work done by the system (gas) on the environment is given by the formula: 
W = PΔV, where P is the constant pressure and ΔV is the change in volume.

Here, P = 50,000 Pa and ΔV = (0.55 - 0.40)m³ = 0.15 m³

Therefore, W = (50,000 Pa) x (0.15 m³) = 7500 J

Hence, the correct answer is (C) 7500 J.
