Your company has the skills and capacity to build 6000 units. The SW/HW engineers estimate the build costs at: 1) one-time setup cost of $30,000; and 2) production cost of $60/unit. The test/quality assurance personnel inform you that a percentage of the units may be defective as shown below:

% probability     40%       30%       20%      6%         4%
