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

### Instruction:
Mabel planted 4 tomato plants. One tomato plant bore 8 tomatoes and another bore 4 more tomatoes than the first. The two remaining plants each bore three times the number of tomatoes as the first two plants combined. How many tomatoes does Mabel have?

### Response:
 Mmea mmoja wa nyanya ulizaa nyanya 8 + nyanya 4 zaidi ya ya kwanza = 8 + 4 = <<8+4=12>>12 nyanya.
Mimea miwili ya kwanza ilizaa 8 + 12 = <<8+12=20>>20 nyanya.
Kila mmea wa nyanya uliobaki ulizaa 3 * 20 = <<3*20=60>>60 nyanya.
Mabel ana jumla ya nyanya 8 + 12 + 60 + 60 = <<8+12+60+60=140>>140.
