Answer:
Consumer's surplus is $11
Explanation:
What is a consumer's surplus?
Consumer's surplus is the difference between amount (price) that a buyer(consumer) eventually pays to acquire a product and the amount he was willing to pay.
There is a surplus if the amount that a consumer pays to acquire a product is less than he was willing to pay.
In the question, the consumer was willing to pay $79 but he eventually paid $68
Therefore, consumer's surplus is $79 - $68
$11
