Agroup of friends would like to play bowling. they would have to pay $4.45 for a game or pay $28.95 per hour. under which circumstance would they have to pay for the hourly cost? explain.

(this was on one of my assignments and it was meant to be a hard question but isn't it common sense to say if they stayed for an hour? but i'm pretty sure that is not the answer. they are probably looking for which would be a better cost but i'm not sure)
