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

### Instruction:
Gordon owns 3 restaurants, his first restaurant serves 20 meals, his second restaurant serves 40 meals, and his third restaurant serves 50 meals per day. How many meals do his 3 restaurants serve per week?

### Response:
 Gordon hutoa chakula cha mlo 20 x 7 = <<20*7=140>>140 kwa wiki katika mkahawa wake wa kwanza.
Anatoa chakula cha mlo 40 x 7 = <<40*7=280>>280 kwa wiki katika mkahawa wake wa pili.
Na anatoa chakula cha mlo 50 x 7 = <<50*7=350>>350 kwa wiki katika mkahawa wake wa tatu.
Hivyo, anatoa jumla ya chakula cha mlo 140 + 280 + 350 = <<140+280+350=770>>770 katika mikahawa yake yote kwa wiki.
