<human>:  Kira wants some new music on her phone. She downloads 10 songs in the morning. Later on that day, she finds 15 more songs she likes so she downloads them, and at night a friend of hers recommends 3 more songs she also downloads. Knowing that each song has a size of 5 MB, how much memory space in MB will the new songs occupy?
<bot>: How many songs are downloaded? ** The total number of songs downloaded is 10 songs + 15 songs + 3 songs = <<10+15+3=28>>28 songs
How much space do the new songs take up? ** The total size of the songs is 28 songs x 5MB/song = <<28*5=140>>140 MB
