How much of Fred's wage income is included when calculating his total income?

To determine how much of Fred's wage income is included when calculating his total income, it is essential to understand the components that make up total income for tax purposes. Typically, total income includes all sources of income, including wages, salaries, bonuses, and any other earnings before deductions such as taxes or retirement contributions.

In this case, if Fred earned a total wage income that is indicated as $90,000, then all of that income would indeed be included when calculating his total income. Other forms of income such as investment returns, rental income, or other deductions are not specified here but would generally be considered separately to derive at total income.

The correct answer focuses solely on wage income without additional adjustments or deductions being applied, which confirms that the entire wage figure is included in the total income calculation. Therefore, Fred’s total income would reflect the full wage amount of $90,000, aligning with the principles of total income determination for tax calculations.
