Final answer:
The correct expression representing the taxable income of a married person claiming two children who jointly earned $90,000 in 2015 is B. 90000 - 8000 - 12600, which takes into account the standard deduction and personal exemptions for the taxpayer, spouse, and two children.
Step-by-step explanation:
The expression that represents the taxable income of a married person claiming two children filing jointly who earned $90,000 in 2015 is calculated by subtracting the standard deduction and personal exemptions from the earned income. The standard deduction for a married couple filing jointly in 2015 was approximately $12,600, and the personal exemption was around $4,000 per person. As a married couple claiming two children, this equates to four personal exemptions (for the taxpayer, spouse, and two children).
Therefore, the correct calculation for this scenario would be:
Taxable Income = Earned Income - Standard Deduction - (Personal Exemption x Number of Exemptions)
This simplifies to:
Taxable Income = $90,000 - $12,600 - ($4,000 x 4)
Taxable Income = $90,000 - $12,600 - $16,000
Taxable Income = $61,400
So, the correct expression from the given options would be:
B. 90000 - 8000 - 12600
