Translation of "en of" into English

Het is onmogelijk te weten welk aanbod is gedaan... en of Montana zich eraan zou houden.

Impossible, certainly, to know what offer was made, and if made, would be honored by Montana in the act.

Dat geeft geen antwoord op de vraag of rekwirante hogere tarieven had kunnen aanvragen en of zij dat inderdaad had moeten doen.

That does not answer the question whether the appellant could have applied for higher charges or whether it should indeed have done so.
