Final answer:
The question pertains to historical financial details of Andrew Carnegie's properties in Dunfermline and Skibo Castle. While specific numbers are not accessible without in-depth research, Carnegie is known to have invested heavily in the renovation of Skibo Castle to transform it into a luxurious estate.
Step-by-step explanation:
The question seems to refer to historical financial aspects concerning properties associated with Andrew Carnegie, a prominent industrialist and philanthropist. The Carnegie rent at Dunfermline would pertain to the rental income or property value associated with Carnegie's birthplace, which he later transformed into public libraries and institutions. On the other hand, the fix-up cost of Skibo refers to the renovation expenses that Carnegie incurred for Skibo Castle in Scotland after he acquired it in the late 19th century.
Exact figures for the rent at Dunfermline or the refurbishment costs for Skibo Castle are not readily available in the public domain and would require specific historical financial records research. It is known, however, that Carnegie spent a significant amount of money to refurbish Skibo Castle, turning it into a luxurious estate where he would spend his summers. The improvements included modern amenities of that period, indicative of his wealth and commitment to enhancing his properties.
