Answer:
Taxable income is $48,000
Explanation:
The computation of the taxable income is shown below:
= Alex AGI + Revenue - standard deduction
= $42,000 + $18,000 - $12,000
= $48,000
We simply added the Adjusted Gross income (AGI) and revenue and then deducted the standard deduction which is given in the question.
The other information which is given in the question is not relevant for the computation part. Hence, ignored it
