Patricia couldn't believe it. The small piece of undeveloped property adjacent to her restaurant just went up for sale! She'd been waiting for this day for years; she had dreamed of a lovely garden with outdoor customer seating. Given the trend for rustic environments, she could set out her existing dining tables and be ready for outdoor seating immediately. She even had financing available for this purchase. The timing might be tricky though; her location was one of many under the corporate umbrella, and executives had just rolled out more stringent goals for each location. Patricia's location generated a 12% ROI last year and was on track to maintain that level this year. Patricia is evaluated on the following for her location: (1) maintaining or improving ROI and (2) generating positive EVA. The property was listed for $350,000, and she would need to finance all of it. Corporate's tax rate was 24%, its average debt rate was 4%, and its cost of equity was 8%. Currently, corporate's financial position reflected 60% debt and 40% equity financing. The purchase of this land would bump up the debt proportion to 65%. Still. Patricia anticipated additional operating income of $18,900 associated with this new space through year-end. What is the corporate WACC assuming Patricia (1) does not purchase the property and (2) does purchase the property? (Round answers to 1 decimal place, e.g. 15.2\%.)
