I Cecilia performed a ballet solo forfour performances over the weekend. The rst one was super exciting and she enjoyed it very much. The second performance was fun, but not as exciting. The third performance was a little less fun than the second performance, but she still enjoyed performing the solo. By the time of the last performance, she was completely exhausted and could not wait until the performance was over. She did not enjoy the last performance at all. Cecilia's utility: Remained the same with each passing performance Was unbounded with each passing performance Increased with each passing performance Decreased with each passing performance
