Final answer:
Dan would be eligible for a tax credit of $510 if the items qualify for a 30% energy-efficient home improvement tax credit, based on the total cost of $1850 for his purchases. The correct option is a. $510
Step-by-step explanation:
Dan made two purchases for home improvements: an exterior door for $500 and 3 energy-efficient windows at $450 each. To find the total cost, we can calculate:
$500 for the door + (3 windows × $450 per window) = $500 + $1350 = $1850.
If these items qualify for an energy-efficient home improvement tax credit, and assuming the tax credit is 30% of the total cost based on the given reference chart, we calculate:
30% of $1850 = 0.30 × $1850 = $555.
The tax credit amount closest to $555 from the given options is $510.
However, it is important to note that actual tax credits are subject to specific government rules. This answer is based on the assumption of a 30% credit, but the exact percentage for a real-world scenario could vary and would need to be verified with current tax laws.
The correct option is a. $510
