Answer:
Zack's adjusted gross income
His adjusted gross income is equal to his gross income minus eligible deductions.
Adjusted gross income (AGI) = gross income - deductions for AGI
= $74,000 - $5,000
= $69,000
Zack's taxable income
His taxable income is equal to his AGI minus itemized deductions minus tax prepayments minus tax credits.
Taxable Income = $69,000 - $2,500 - $8,400
= $58,100
