Explanation:
The correct answer is a) 163,200. When calculating how much Mary's salary is after a 2% raise on her original salary of $160,000, we need to determine the increase in her pay and then add that to her original salary. A 2% raise means that for every $100 Mary earns, she will receive an additional $2. To calculate the amount of the raise, multiply her original salary by 2%, or 0.02:
Salary increase = Original Salary × Percentage Increase
Salary increase = $160,000 × 0.02
Salary increase = $3,200
Now, add this increase to her original salary:
New Salary = Original Salary + Salary Increase
New Salary = $160,000 + $3,200
New Salary = $163,200
So, after the raise, Mary's salary will be $163,200.
