Final answer:
The total amount of Illinois transfer tax due for Sonja's house is $250.60.
Step-by-step explanation:
To find the total amount of Illinois transfer tax due, we need to determine the tax rate and calculate it based on the selling price of Sonja's home.
In Illinois, the transfer tax rate is $1.00 for every $1,000 of the selling price. So, the tax rate is 1/1000 or 0.001.
Let's calculate the transfer tax:
Tax = Tax rate x Selling price
Tax = 0.001 x $250,600
Tax = $250.60
Therefore, the total amount of Illinois transfer tax due is $250.60, which is closest to option d) $376.50.
