Final answer:
The amount Bart used above his credit limit is $316 by subtracting the credit limit from the car's cost. The closest matching option given is B) $316.49.
Step-by-step explanation:
To calculate the amount of credit Bart used above his limit, we need to subtract the credit limit from the cost of the car he purchased. The credit limit is $2793, and the car costs $3109.
Amount above limit = Cost of the car - Credit limit
Amount above limit = $3109 - $2793
Amount above limit = $316
Therefore, the amount Bart used above his credit limit is $316. Comparing this result with the multiple-choice options, we can see that the closest match is option B) $316.49, which might be due to a slight difference in the last two digits that are probably irrelevant for this calculation or possibly a typo in the question. However, based on the credit limit and the cost of the car provided, the correct calculation results in $316.The closest matching option given is B) $316.49.
