Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Elsa gets 500 MB of cell phone data each month. If she spends 300 MB watching Youtube and 2/5 of what's left on Facebook, how many MB of data does she have left?

### Response:
 Elsa anabakiwa na 500-300 = <<500-300=200>>200 MB ya data baada ya kutazama Youtube.
Kisha, 200*(2/5) = <<200*(2/5)=80>>80 MB inatumika kwenye Facebook.
Hatimaye, Elsa anabakiwa na 200-80 = <<200-80=120>>120 MB ya data.
