Final answer:
The Barnetts would likely have itemized their deductions if such deductions were higher than the standard deduction, reducing their taxable income. In absence of further details, we cannot ascertain the exact comparison between their itemized deductions and the standard deduction.
Step-by-step explanation:
When the Barnetts itemized on their tax returns, they compared their itemized deductions to the standard deduction to determine which was higher. Typically, taxpayers will itemize deductions if their total itemized deductions are higher than the standard deduction, as this would lower their taxable income and thus reduce the amount of tax they owe. If, however, their itemized deductions were lower or equal to the standard deduction, it would be more beneficial for them to choose the standard deduction. Without additional information about the Barnetts' specific deductions, we cannot definitively say whether their deductions were higher, lower, or equal to the standard deduction.
