Question

For the past three months, grace used her cell phone for 43 minutes, 62 minutes, and 57 minutes. How many minutes would she have to use her cell phone this month for the average usage over the four months to be 55 minutes

Answer 1

She would only have to use her phone for one more minute for the average to be 55 minutes

Answer 2

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! :)
