Answer:
$12
Explanation:
The next best alternative is reading a new book at $12; therefore, the opportunity cost of taking the stroll through the park is $12.
In this case, steaming the movie is $5 and taking a nap is $7 which are lower than $12 which means these two values are not included in the final opportunity cost.
If the question asked what is the opportunity cost of reading a new book (and taking a walk in the park isn't an option) then the $7 value of taking a nap would be the opportunity as it will be the next best thing from reading a new book.
