If Karen gets up early and studies three hours for her test, she is likely to get an A. If she sleeps in, she will probably get a C. What is the opportunity cost of sleeping in?

Respuesta :

I think the answer is three additional hours of study.
the opportunity cost is what she loses if she chooses to sleep in

if she studies, she will probably get an A and lose 3 hours of sleep
if she sleeps in, she will probably get a C and gain 3 hours of sleep

so the opportunity cost of sleeping in is the A that she could have gotten if she had studied
