Suppose 89 kW is to be transmitted over two 0.150 Ω lines.

Estimate how much power is saved if the voltage is stepped up from 180 V to 1800 V and then down again, rather than simply transmitting at 180 V . Assume the transformers are each 99%efficient.

Express your answer using two significant figures.
