University Health System has three divisions: Real Estate, with an 8 percent cost of capital; Health Services, with a 10 percent cost of capital; and Managed Care, with a 12 percent cost of capital. The System's risk adjustment procedures call for adding 3 percentage points to adjust for high risk and subtracting 2 percentage points for low risk. Construct a diagram such as the one in Exhibit 12.9 that illustrates the range of project costs of capital for the system.
