Everlasting Bubbles, Inc., produces multicolored bubble solution used for weddings and other events. (Click the icon to view the master budget income statement.) Everlasting Bubbles' plant capacity is 52,500 kits. If actual volume exceeds 52,500 kits, the company must expand the plant. In that case, salaries will increase by 10%, depreciation by 15%, and rent by $5,000. Fixed utilities will be unchanged by any volume increase
