Lisa is choosing between three alternatives: a) working at her job that pays 60 dollars; b) writing a term paper which she values at 40 dollars; or c) going out with a friend, which she values at 80 dollars. the opportunity cost of writing the term paper is:

$80

Explanation:

Opportunity cost is the benefit that is foregone for an individual by choosing one alternative over other alternatives available to him.

If the opportunity cost is lower for an individual then this will benefit him whereas if the opportunity cost is higher then this will not benefit the individuals.

The opportunity cost of writing a term paper is $80 that she values by going out with a friend and it is the higher cost alternative.

88 because 4 plus 4 equals 8. 40 plus 40 equals 80. 80 plus 8 equals 88
