Susan’s cell phone allows her to use 960 minutes per month with no additional charge. she has 188 minutes left for this month. how many minutes has she already used this month?

Amovie streaming service charges it’s customers $15 a month. martina has $98 saved up. will she have any money left over if she pays for the maximum amount of months she can afford? explain.
