Imagine that Alina’s shower leaks and she calls the plumber. The plumber tells her that the problem is caused by either a leaky drain or a cracked shower pan, but never both. He also tells her that, in his experience, a leaky drain is the cause of the problem in about 90%90% of cases. If he discovers that the drain is the problem, he can fix it for $250$250. If he discovers that the shower pan is the problem, he must charge $2500$2500 instead. What is the expected value of the repair price? Please round your answer to the nearest whole dollar.
