To find the executive's monthly salary, we need to subtract the Christmas bonus from her total annual earnings.

Step 1: Calculate the total annual earnings after subtracting the Christmas bonus:
Total annual earnings = 98700 dollars - 5300 dollars
Total annual earnings = 93400 dollars

Step 2: Divide the total annual earnings by 12 to find the monthly salary:
Monthly salary = Total annual earnings / 12
Monthly salary = 93400 dollars / 12
Monthly salary ≈ 7783.33 dollars

Therefore, the executive's monthly salary is approximately 7783.33 dollars.
