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

### Instruction:
Mr. Roberts can buy a television for $400 cash or $120 down payment and $30 a month for 12 months. How much can he save by paying cash?

### Response:
 Gharama ya televisheni ni $400.
Gharama ya televisheni kwa kutumia mpango wa malipo ya kila mwezi ni $120 + 12 x $30 = $120 + $360 = $480.
Anaweza kuokoa $400 - $480 = $<<400-480=-80>>-80.
