Jeff pay $2,300 for his computer.
b. $2,300
Explanation:
Consumer surplus can be defined as the amount that the consumer is willing to pay for a product or a service. The word surplus is a synonym for something extra or excess. It corresponds to the extra benefit that the consumer gets while buying something which may be the result of some discount, sale, or negotiation. Â
Jeff realizes a consumer surplus of $700 while purchasing a laptop of $3000. As the consumer surplus is $700,
the amount Jeff has paid for the laptop is: $3000 - $700
                     : $2300
