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

### Instruction:
Quinten sees three buildings downtown and decides to estimate their heights. He knows from a book on local buildings that the one in the middle is 100 feet tall. The one on the left looks like it is 80% of the height of the middle one. The one on the right looks 20 feet shorter than if the building on the left and middle were stacked on top of each other. How tall does Quinten estimate their total height to be?

### Response:
 Anakadiria jengo upande wa kushoto kuwa na urefu wa futi 80 kwa sababu 100 x .8 = <<100*.8=80>>80
Urefu jumla wa majengo ya kushoto na katikati ni futi 180 kwa sababu 100 + 80 = <<100+80=180>>180
Anakadiria jengo upande wa kulia kuwa na urefu wa futi 160 kwa sababu 180 - 20 = <<180-20=160>>160
Anakadiria urefu jumla kuwa futi 340 kwa sababu 160 + 180 = <<160+180=340>>340
