To calculate Matthew's net pay with all mandatory taxes included, we need to subtract the total taxes from his earnings of $1,000.
- Federal taxes: $94.12
- Social Security tax: 6.2% of $1,000 = $62
- Medicare tax: 1.45% of $1,000 = $14.50
Now, we add the taxes together:
- Total taxes = Federal taxes + Social Security tax + Medicare tax
- Total taxes = $94.12 + $62 + $14.50 = $170.62
Now, we subtract the total taxes from his earnings:
- Net pay = Earnings - Total taxes
- Net pay = $1,000 - $170.62 = $829.38
So, Matthew's net pay is D. 829.38.
