The local hockey complex in Detroit has requested bids for ice maintenance for the upcoming 20-week season, and four companies have submitted proposals. The four companies that bid on the job all have different pricing structures. The ice rink in question has a regulation 19,000-square-foot surface, and all companies provide their variable cost pricing in terms of dollars per 100 square feet of ice. Variable costs typically increase during the season due to expensive Zamboni maintenance. Company Fixed Cost/Week ($) Cost/Sq. Ft. Weeks 1-10 ($) Cost/Sq. Ft.
