[問題]OG的句意問題

[yoyu.tw]

A certain fishing boat is chartered by 6 people who
are to contribute equally to the total charter cost of
$480. If "each" person contributes equally to a $150
down payment, how much of the charter cost will
each person still own ?

我寫ㄉ時候 看到 each
but 答案是 （480-150）/6 why?
雖然知道很丟臉 還是想問^^

我覺得題目是問說─
"如果每個人已平均分攤了$150，那每個人還需要分攤多少元?"
