Okay, so for this question you would add. 

You would add the minutes that she used for her cell phone. 

Fourty - Three plus  Sixty - Two plus Fifty - Seven
                One - Hundred - And - Five
         Equals One - Hundred - And - Sixty - Two

Then, you would add One - Hundred - And - Sixty - Two and Fifty - Five.

One - Hundred - And - Sixty - Two plus Fifty Five

Equals Two - Hundred - And - Seventeen


So Your Answer Will Be "Grace Spent 217 minutes on her cell phone.

Hope This Helps! :)
