In Plutarch Enterprises, 60% of the employees are marketers, 30% 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?	Select the correct option:
A) $80,000 B) $130,000 C) $260,000 D) $290,000 E) $320,000
For sake of ease, let's say there are 10 employees:6 marketers, 3 engineers, and 1 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 (3 * $80,000)   &gt;&gt;&gt; $800,000 - $300,000 - $240,000 = $260,000.   The correct answer is $260,000.
