Earn to Escape 6

Blake LaVista has a challenge and a way to make some great cash. Every time she can escape she earns 100, up to 300 and if not she has to successfully answer a question. Her arms are then bound by rope to her legs and she's gagged. She escapes and goes into round two. Next, she's placed in a metal bondage device for her arms and legs and has to answer questions. Finally, she's bound a third time with her arms behind her back and has to answer more questions. How much did Blake earn?
