Answer:
The opportunity cost = $2.5
Explanation:
Given:
You own a building that has four possible uses: a cafe, a craft store, a hardware store, and a bookstore. The value of the building in each use is $2,000; $3,000; $4,000; and $5,000, respectively.You decide to open a hardware store.
<u>Question asked:</u>
The <u>opportunity cost of using this </u><u>building for a hardware store</u> ?
<u>Solution:</u>
As we know:

What you sacrifice = Value of a cafe + Value of a craft store + Value of a bookstore
= $2000 + $3000 + $5000 = $10,000

= $4000
Thus, the opportunity cost of using this building for a hardware store is $2.5
