Step-by-step explanation:
The correct answer is option A. $166,600.
To find the new salary after a 2% raise, we can multiply the original salary by 1 plus the decimal equivalent of the percentage increase. In this case, the decimal equivalent of 2% is 0.02. So, Mary's new salary would be:
New Salary = Original Salary + (Original Salary x Percentage Increase)
New Salary = $160,000 + ($160,000 x 0.02)
New Salary = $160,000 + $3,200
New Salary = $163,200
Therefore, Mary's salary after the raise is implemented is $163,200, which corresponds to option A.
