a company has 15 managers and 75 associates . the 15 managers have an average salary of $ 120,000 . the 75 associates have an average salary of $ 30,000 . what is the average salary for the company ?
"the 15 managers have an average salary of $ 120,000 . the sum of their salaries is : sum = ( average ) * ( number of salaries ) = $ 120,000 * 15 = $ 1 , 800,000 the 75 associates have an average salary of $ 30,000 . the sum of their salaries is : sum = ( average ) * ( number of salaries ) = $ 30,000 * 75 = $ 2 , 250,000 when we add those two sums , we get the total payroll of all 90 employees . $ 1 , 800,000 + $ 2 , 250,000 = $ 4 , 050,000 so , we have 90 employees , and together they earn $ 4 , 050,000 , so the average is average = $ 4 , 050,000 ÷ 90 = $ 45,000 answer : b ."
