Tyler Weinrich, a single investor in the 15% federal tax bracket, owns 150 shares of Newmont Exploration. The stock has risen from its price of $40 a share to $75 a share. Because the board of directors believes that Newmont Exploration will be more actively traded in the $40 to $60 range, it has just announced a 3-for-1 stock split. Assuming no other information came out about Newmont Exploration, how many shares would Tyler have and what would be their price after the split?
