DiPitro's Paint and Wallpaper, Inc., needs to raise $$1$ million of common stock to finance plant expansion. In discussions with its investment bank, DiPitro's learns that the bankers recommend a gross price of $$25$ per share and that $45,000$ shares of stock be sold. If the net proceeds on the stock sale leaves DiPitro's with $$1$ million, calculate the underwriter's spread on the stock issue.
