Question a power plant operates at 285 efficiency during, Ask an Expert

Academics

Question: A power plant operates at 28.5% efficiency during the summer when the seawater used for cooling is at 20.0°C. The plant uses 305°C steam to drive turbines.

Part A: If the plant's efficiency changes in the same proportion as the ideal efficiency, what would be the plant's efficiency in the winter, when the seawater is at 12.5°C?

Please show work I think I have the answer just not positive.
