Concept:Opportunity cost is the value of the next best alternative that must be given up when a choice is made.
Explanation:The consumer has only
$10 to spend.
Buying the pair of shoes costs
$10, leaving no money for any other item.
With the same
$10, the consumer could instead buy the handbag for
$7 and the jewelry for
$3, together costing exactly
$10.
The dress costs
$20, which is not affordable with the available
$10.
Therefore, the best alternative sacrificed by choosing the shoes is the handbag and jewelry.
Answer:Handbag and Jewelry.
