If a salary of $50,000 is increased by 10% and then decreased by 10%, what is the final salary?
Step 1: Start with the original salary of $50,000.
Step 2: Calculate the increase by multiplying the salary by 10%. This is done by multiplying $50,000 by 1.10 (which represents the original salary plus 10%).
Step 3: The result of the increase is $55,000.
Step 4: Now, calculate the decrease by taking the new salary of $55,000 and multiplying it by 10% decrease. This is done by multiplying $55,000 by 0.90 (which represents the new salary minus 10%).
Step 5: The result after the decrease is $49,500.
