I really don't get this question and my work's due tomorrow any help is really appreciated!

A game consists of rolling a dodeacahedral (12 faced) die and receiving the dollar amount equivalent to the roll. If the cost to play the game is $5 what is the expected payout for each round that is played?

We're on discrete probability chapter, according to the back of my text book the answer should be $5

I hope someone can help me, thanks in advance!!
