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

### Instruction:
Big Dig Mining Company mines three different types of ore: copper, iron, and nickel. Across all their mines, 10% of their output is nickel, 60% is iron, and the rest is copper. They mine 720 tons of nickel a day. How many tons of copper does Big Dig Mining Company mine daily?

### Response:
 Hebu R iwe uzalishaji wa jumla wa madini ya kampuni.
Kati ya uzalishaji wa Big Dig, 100 - 10 - 60 = <<100-10-60=30>>30% ni nikeli.
Kwa kuwa 720 ni 60% ya 100% ya uzalishaji wao, 720 / R = 60 / 100
Hivyo, uzalishaji wa jumla wa kampuni ni R = 100 * 720 / 60 = <<100*720/60=1200>>1200 tani.
Kwa kuwa 30% ya uzalishaji wao ni nikeli, wanachimba 1200 * 30 / 100 = <<1200*30/100=360>>360 tani za shaba kila siku.
