Education of girls Maaser money for tuitition?

Igros Moshe (YD II:113) Question: Can tuition for a daughter’s Beis Yakov be paid from Maaser? Answer  There is certainly a distinction between sons and daughters in Torah study since the father has a clear obligation to educate his son in Torah even if he has to pay for it. And thus it is a Torah obligation and he should not use maaser money. In contrast there is no obligation to educate his daughter and if there is need then it is possible to pay from masser money. .However in America the law requires girls to be educated and due to G-d’s kindness they are allowed to study in proper religious schools.  Thus if she doesn’t go to Beis Yakov  then she would be required to attend public school where she will not get religious training. However he has an obligation that she get a proper religious education even if it costs him money and thus he actually has an obligation to send her to beis Yakov in America so Maaser money can not be used. However according to the Mishneh Berura the obligation is to save her from the goyim and thus it is not a special obligation on the father but a general one and accordingly maaser money could be used  However this is problematic since the halacha is that the father is obligated to properly educate his daughter in proper faith mitzvos and avoiding sin.  Therefore it is obvious that the father needs to pay for the education of both sons and daughters and therefore maaser can not be used for either. It is only if additional payment is required then for both sons and daughters maaser can be used.
