Answer:
The opportunity cost for a year will be $240,000.
Explanation:
The opportunity cost of any decision is the second-best alternative that is given up or sacrificed.
Here, the manager has a farm of 100 acres of land.
If he sells it to a developer for $40,000 per acre, he will get $4,000,000 for the whole land.
He can invest this amount and get an interest of 6% per year.
The opportunity cost of keeping the farm to the manager himself will be
= 6% of $4,000,000
=
= $240,000
