Answer:
540 megabytes
Step-by-step explanation:
We will first need to find out how much space a<em> singular song</em> will take up. We will do this by <em>the storage taken up (884) by the number of songs she has:</em>
884 / 221 = 4 mb taken up per song
Then we want to find out how many megabytes <em>135 of these songs take up</em>, so we will multiply the <em>mb taken up per song (4) by the number of songs we want to find (135)</em>:
4 x 135 = <em>540 megabytes</em>
