Answer:
There are NO real solutions to this equation as per the study of its discriminant.
Step-by-step explanation:
In order to answer the question, one needs to examine the "discriminant" associated with this quadratic equation.
Recall that the discriminant of a quadratic equation of the form:
is given by:
in our case :
Then the discriminant becomes:
The discriminant is then a negative number, which means that there are NO real solutions (its solutions must involve imaginary numbers)
Let
be the average salary of an employee. Since the salary of the business man is 6 times the average salary of an employee, his salary will be
. We also know that the sum of the salary of the businessman and the average salaries of his 10 employees is 640000, so:
Solving for
:
The average salary of an employee is 4000, so the salary of the businessman will be
.
We can conclude that the business man's salary that year was 24000.
