In Plutarch Enterprises, 70% of the employees are marketers, 10% 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?	Options:  A) $80,000  B) $130,000  C) $240,000  D) $370,000  E) $320,000
For sake of ease, let's say there are 10 employees: 7 marketers, 1 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 (7 * $50,000) and the engineers ( $80,000)   &gt;&gt;&gt; $800,000 - $350,000 - $80,000 = $370,000.   The correct answer is $370,000.
