Given:
c = 80 - 3.22n
where
c = recording time available
n = number of songs recorded
When c = 0, then
80 - 3.22n = 0
n = 80/3.22 = 24.845
Answer:
The zero of the function is 24.845.
Because songs are countable, it means that after 24 songs are recorded, there will be no room to record additional songs.
Furthermore, there will not be enough room to finish recording the
25-th song.
