Kgetsana ya ga Jillian e ne e le bokana bongwe go feta makgetlho a le mararo a tlhotlhwa ya ditlhako tsa gagwe ka $20. Fa ditlhako tsa gagwe di ne di le $80, kgetsana ya gagwe e ne e le bokana?

Gabriel and Luri each own a portable media player that can store up to 100 songs. Gabriel has 20 songs on his player while Luri has 3 times as many songs. How many fewer songs can Luri add to his player than Gabriel can add to his?
Sa ntlha, atisa tlhotlhwa ya ditlhako ka makgetlho a le mararo: $80 * 3 = $<<80*3=240>>240
Morago ga foo, fokotsa ka $20 go bona tlhotlhwa ya kgetsana: $240 - $20 = $<<240-20=220>>220
#### 220 

Gabriel can still store 100 - 20 = <<100-20=80>>80 songs.
Luri has 20 x 3 = <<20*3=60>>60 songs stored in his player.
Thus, Luri can still store 100 - 60 = <<100-60=40>>40 songs.
Luri can add 80 - 40 = <<80-40=40>>40 fewer songs to his player than Gabriel.
