Q17. A single share of a stock was purchased prior to the company's release of its quarterly report. There is a 58% chance that the company will meet the quarterly sales expectations for its new product two weeks from now, and the value of the stock will go to $440. Otherwise, the company will not meet the quarterly sales expectations, and the value of the stock will go down to $100. What is the expected value of the stock two weeks from now? (Round to the nearest dollar. Do not enter $ sign.)
