question 85

Multiple Choice

• A) gross salary = net salary - tax; total energy = free energy - entropy
• B) net salary = gross salary - tax; free energy = total energy - entropy
• C) tax = gross - net salary; entropy = total energy - free energy
• D) gross salary = tax - net salary; total energy = entropy - free energy
• E) net salary = gross salary + tax; free energy = total energy + entropy
