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

### Instruction:
 Samaki aina ya herring ina mafuta ya 40 oz, papa ina mafuta ya 20 oz, na pike ina mafuta ya 10 oz zaidi ya papa. Ikiwa Ellianna alipika na kuwahudumia samaki 40 kwa kila aina, hesabu ni mafuta mangapi aliwahudumia.


### Response:
 Samaki aina ya herring ina mafuta ya 40 oz, papa ina mafuta ya 20 oz, na pike ina mafuta ya 20 + 10 = 30 oz.
Jumla ya mafuta katika huduma moja ni 40 + 20 + 30 = <<40+20+30=90>>90 oz.
Ellianna aliwahudumia 40 * 3 = <<40*3=120>>120 huduma.
Jumla ya mafuta aliyo hudumia ni 120 * 90 = <<120*90=10800>>10800 oz.
