Final answer:
Without additional information about Rey's financial details, we cannot determine the exact amount of capital gains deduction he can apply against his taxable income. Capital gains deductions are based on specific realized gains and adjusted by filing status and additional deductions or exemptions.
Step-by-step explanation:
To determine the amount of the capital gains deduction available for Rey to use against his taxable income, we need specific information about Rey's financial situation. Considering the basic concepts of taxation, the calculation of taxable income is the adjusted gross income minus deductions and exemptions. The capital gains deduction is a tax benefit that allows individuals to reduce their taxable income by a certain amount based on the capital gains they have realized. However, without details of Rey's capital gains, deductions, and exemptions, it is not possible to provide the exact amount that Rey can deduct. For a single individual in 2010, the standard deduction and exemption totaled $9,350, which would be subtracted from the adjusted gross income to determine taxable income. To provide an accurate figure for Rey's capital gains deduction, additional information such as the amount of capital gains, his filing status, and any other applicable deductions or exemptions would be required.
