a certain company had a total annual expenditure of 2.1 ∗ 10 ^ 7 on employee salaries last year . if the company employed 420 people , what was the average employee salary ?
"given : total annual expenditure of 2.1 ∗ 10 ^ 7 on employee salaries total employees = 420 observe that 420 * 5 = 2100 therefore try to bring the numerator in terms of 2100 average salary = ( 2100 * 10 ^ 4 ) / 420 = 5 * 10 ^ 4 = 50,000 option e"
multiply(divide(multiply(2.1, multiply(10, 7)), 420), const_100)
