Suppose your company needs $10 million to build a new assembly line. Your target debt-equity ratio is 3.0. The flotation cost for new equity is 20%, but the flotation cost for debt is only 5%.

a) What do you think about the rationale behind borrowing the entire amount?

b) What is the true cost of building the new assembly line after taking flotation costs into account?
