1. IfXis $5,000, R-15% and BV is $50,000, what is AE? -5000-(15%*50000) -2500 2. IfXis $25,000, R-18% and BV is $125,000, what is AE? -25000-(18 % 125000) 2500 3. Assume the firm in requirement 2 can increase x to $30,000 by instituting some cost-cutting measures. What is the new AE? -30000-(18 % 125000) 7500 4. Assume the firm in requirement 2 can divest $25,000 of unproductive capital with X falling by only $2,000. What is the new AE? -25000-2000-(18% *(125000-25000)) 5000 5. Assume the firm in requirement 2 can add a new division at a cost of $40,000, which will increase X by $7,600 per year. Would adding the new division increase AE? -25000+7600-(18% *( 125000+40000)) 2900 FALSE Assume the firm in requirement 1 can add a new division at a cost of $25,000, which will increase X by $3,500 per year.
