A benchmark index has three stocks priced at $34, $57, and $67. The number of outstanding shares for each is 405,000 shares, 515,000 shares, and 663,000 shares, respectively. If the market value weighted index was 920 yesterday and the prices changed to $34, $54, and $70, what is the new index value? 910, 915, 920 or 925? Thanks!
