Questions Concern a different wall on a different island with families A, B, and C.
The ratio MBA : MBB : MB C is 5:2:1 at any thickness. For example, at a thickness of 0 feet, MBA = $1,000, MBB = $400, MBC = $200, and at a thickness of 5 feet, MBA = $500, MBB = $200, MBC = $100. The marginal cost (MC) of building an additional foot of thickness is $800. Draw the diagram, label the curves (lines), and show numbers.
