Answer 1

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! :)
