Comparing Bob's Salary Changes: 2009-2011

Question:

Will Bob's 2011 salary be more or less than his salary back in 2009?

Answer:

If Bob's 2011 salary is more than his 2009 salary, then his 2011 salary will be more than his salary back in 2009.

Explaining the Salary Changes:

In 2009, Bob makes a certain salary, denoted as $X. In 2010, Bob gets a raise of 8.5%. This means his 2010 salary would be $X * (1 + 0.085).

Then, in 2011, the company goes through difficult times and decreases Bob's salary by 8.5%. Therefore, his 2011 salary would be calculated as Bob's 2010 salary * (1 - 0.085).

To compare Bob's 2009 and 2011 salaries, we can analyze the changes due to the raise and decrease. If Bob's 2011 salary is more than his 2009 salary, it indicates a net increase in his salary over the years.

Hence, based on these calculations, we can determine whether Bob's 2011 salary will be more or less than his salary back in 2009.

Conclusion:

Comparing the salary changes from 2009 to 2011 reveals whether Bob's income has increased or decreased over the years. This analysis helps in understanding the impact of salary adjustments on an individual's overall earnings.
