In Plutarch Enterprises, 60% of the employees are marketers, 20% are engineers, and the rest are managers. Marketers make an average salary of $50,000 a year, and engineers make an average of $80,000. What is the average salary for managers if the average for all employees is also $80,000?	Choose the correct choice from the following:
A) $80,000
B) $130,000
C) $240,000
D) $290,000
E) $340,000
For sake of ease, let's say there are 10 employees: 6 marketers, 2 engineers, and 2 manager.   Average company salary * Number of employees = Total company salary   &gt;&gt;&gt; $80,000 * 10 = $800,000   Subtract the combined salaries for the marketers (6 * $50,000) and the engineers (2 * $80,000)   &gt;&gt;&gt; $800,000 - $300,000 - $160,000 = $340,000.   The correct answer is $340,000.
