Final answer:
The total itemized deductible expenses for Nikki are not $300 but $420.
Step-by-step explanation:
The question is asking whether Nikki's total itemized deductible expenses are $300. To determine the answer, we need to add up all the expenses mentioned: bridge tolls ($30), highway tolls ($50), automobile registration fees ($40), state income taxes ($200), and local income taxes ($100).
Adding these amounts together, we get $30 + $50 + $40 + $200 + $100 = $420. Since the total deductible expenses are $420, the statement that Nikki's total itemized deductible expenses are $300 is False.
