Answer:
C. You should stay and watch the remainder of the show.
Step-by-step explanation:
Here cost of watching the play = $30
Value of seeing the remainder = $10
Value of watching TV = $8
Value of reading a book = $6
Now since the price of ticket is non refundable, $30 is paid, even if the play is left in between, $30 is gone.
In all the cases least cost will be $30
After which if the book is read value = $6
In case of watching TV value = $8
In case of watching the remainder show value = $10
Since maximum value of watching remainder show is maximum with least cost it shall we continued.
Final Answer
C. You should stay and watch the remainder of the show.
