May isang concert ka pupuntahan and then at the same time nagkataon na nagkasabay na meron kayong tryouts sa isang club na gusto mong salihan. so for example pag pinili mo yung tryouts instead of the concert then yung opportunity cost mo yung concert. you going to the tryouts cost you the opportunity to go to the concert.
