Final answer:
Without adequate data on dependents for each job, assuming each role has one dependent, we'd calculate the Net Annual Income for each position and find the average. From there, the monthly average salary can be determined by dividing the Net Annual Income of each position by 12 months.
Step-by-step explanation:
To determine the average salary of all full-time employees with at least one dependent, you would need to use a combination of Excel functions, like IF, AVERAGEIF, or AVERAGEIFS. Unfortunately, the question does not provide adequate data on dependents for each job nor does it specify whether there are multiple employees in these roles or just one. Assuming each role represents one full-time employee with at least one dependent, and each role provided has exactly one dependent, you could simply calculate the average of the net annual incomes of the provided positions and then divide by 12 to find the monthly average salary.
The first step is to calculate the Net Annual Income for each job position by subtracting the taxes (and any other deductions such as social security and medicare if provided, which they are not in this case) from the gross annual salary. For example, for the Customer Care Representative with a gross annual salary of $22,000 and taxes of $2,850:
Net Annual Income = Gross Annual Salary - Taxes
Net Annual Income = $22,000 - $2,850
Net Annual Income = $19,150
Once the Net Annual Income is calculated for each position, the monthly income can be found by dividing the Net Annual Income by 12 months:
Monthly Income = Net Annual Income / 12
