In the example, the direct object was being called for. Why use the "le" form, then?   

Miguel tiene una novia y tu tienes

demasiada ( incorrect answer).  The correct answer is demasiadas

Miguel has one girlfriend and you have too many.

Una novia is singular so why is my answer demasiada wrong.

If está is followed by an adjective & hay by a noun, why is it 'hay niebla' rather than 'está niebla'?

I have gotten confused by a specific use of the personal a.  As I understand it, if you are mentioning a person or group of people, you need a personal a infront of the person.  For example if I am talking about a reporter mentioning Juan, I might say El reportero mencionó a Juan.  It also looks like if I want to say that the reporter mentioned Juan to Ana, I should say  El reportero mencionó Juan a Ana.  

Is this correct?  Is this also a general pattern - i.e. when I would normally use a personal a, but there is an indirect object (Ana), should I always drop the personal a and use the a for the indirect object?

Thanks

Your explanation says that whole hundreds AFTER 200 agree with the noun it precedes, but doesn´t 100 also?

I.e. hay cientas diez chicas?

If not what would be the correct answer?
