Step-by-step explanation:
Jerry will have to pay the whole amount. This is because she has not reported the theft of her card and the credit card company is not liable to pay anything or bear any loss until a report is logged. If she had filed the theft complaint and had blocked the credit card, then the credit card company was liable for the loss. But now in this scenario, she herself took longer to file a theft complaint and the thief made a purchase of $500 from her card, she is solely responsible for this charge.
