In the case of Rockboro Machine Tools Corp (2015 case study) I'm viewing rockboro_case_quetion_1.docx now....No, I am trying to understand how to get to the answer in step by step approach. Thanks

1.to fund an increased dividend payout or a stock buyback, a firm might invest less, borrow more, or issue more stock. Which of those three elements is Rockboro's management willing to vary, and which elements remain fixed as a matter of the company's policy? Thank you.
