Amazonas has three operating divisions: AZ capital (40%), AZ Technology (30%) and AZ Energy (30%). The CFO wants to estimate the cost of capital for each division, to help with capital budgeting. Amazonas is financed 50% by dept, with _D = 0.15. The current risk-free interest rate is 5% and the expected marked return is 10%. The following three competitors have investments similar to those of Amazonas three divisions (with debt practically risk-free):

Company	Equity Beta	E / (D + E)
A in capital	0.6	0.7
B in Technology	1.5	0.8
C in Energy	1.4	0.6

Q1: What is the cost of capital for each division? Q2: What is Amazonas equity beta?
