Andrea is an entrepreneur who has recently opened a business that produces and sells custom wood furniture. Andrea's customers all seem very happy with the quality of her products, and her staff is always busy keeping up with the flow of incoming orders. Recently, business has been so good that Andrea has had to put customers' orders on a waiting list until her staff can get around to working on them. In the best interest of her business, what should be the next step that Andrea takes? A Andrea should expand her business by hiring more staff so that she can process her customers' orders more quickly. B Andrea should decrease the amount of advertising she is doing so that her orders slow down and allow her to catch up. C Andrea should switch to a lumber supplier that provides cheaper, lower quality lumber in order to save money. D Andrea should begin turning customers away to prevent them from becoming frustrated at being put on a waiting list.
