your phone is old and only has enough storage to hold 70 minutes music. so far you have added 25 minutes of music to the phone. you estimated that each song last four minute. what are the possible numbers of additional songs that you can add to your phone?
total storage to hold 70 minutes music.
I have added 25 minutes music.
each song last 4 minute.
The possible number of additional songs that I can add to your phone is "\\large\\frac{70-25}{4}" "\\approx" 11.
