We can store 850 more songs in our mp3 player if we have 3.4 gigabytes of available memory.
Given is 3.4 gigabytes of storage available on an mp3 player and each song is about 0.004 gigabytes
We can write from the given data -
Memory available = [M] = 3.4 gigabytes
Memory needed per song = [m] = 0.004 gigabyte
So, the number of songs that can be stored will be equivalent to -
n = M/m
n = 3.4/0.004
n = 850
Therefore, we can store 850 more songs in our mp3 player.
