(b) The Warm Shoe Co. has concluded that additional equity financing will be needed to expand operations and that the needed funds will be best obtained through a rights offering. It has correctly determined that as a result of the rights offering, the share price will fall from $100 to $95 (hint: $100 is the rights-on-price; $95 is the ex-rights price). The company is seeking $18 million in additional funds with a per-share subscription price of $50. How many rights will it take to purchase one new share?
