Final answer:
The amount due for the student's electricity bill in July is a credit of $351, since their solar panel generated more electricity than what was used. Thus, the correct option is "A".
Step-by-step explanation:
The student is asking how to calculate their electricity bill based on their usage and the amount of electricity generated by their solar panel. They used $1924 worth of electricity and their solar panel generated $2275. To find the amount due, we subtract the amount generated by the solar panel from the amount of electricity used.
$2275 (generated) - $1924 (used) = $351
Since the solar panel generated more electricity than what was used, this results in a negative amount due, meaning they have a credit of $351.
Therefore, the answer is A) $-351.
