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

### Instruction:
 Jana, Sarah alikusanya makopo ya alumini 50 wakati Lara alikusanya makopo ya alumini 30 zaidi. Leo, Sarah alikusanya makopo ya alumini 40 wakati Lara alikusanya makopo ya alumini 70. Walikusanya makopo mangapi chache leo kuliko jana?


### Response:
 Jana, Lara alikusanya makopo ya alumini 50 + 30 = <<50+30=80>>80.
Hivyo, Sarah na Lara walikusanya jumla ya makopo ya alumini 50 + 80 = <<50+80=130>>130 jana.
Leo, Lara alikusanya makopo ya alumini 70 - 40 = <<70-40=30>>30 chache.
Hivyo, Sarah na Lara walikusanya jumla ya makopo ya alumini 40 + 70 = <<40+70=110>>110 leo.
Hivyo, walikusanya makopo ya alumini 130 - 110 = <<130-110=20>>20 chache leo kuliko jana.
