i hope this helps!
It took them 4 days to install 480 chairs which means if they were working at a constant rate they got 120 chairs installed daily. with 360 chairs left that means in 3 days they will finish. so overall, it took the workers 7 days to finish, or a week.
We have the value -0.000125
Since this is negative value the cube number cannot be positive since it will not give an negative answer
hence the answer should be a negative number
this already eliminates the option A, B and D
now we have
![\sqrt[3]{-0.000125}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B-0.000125%7D%20%20)
![\sqrt[3]{(-0.05).(-0.05).(-0.05)}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%28-0.05%29.%28-0.05%29.%28-0.05%29%7D%20%20)
=-0.05 (option C)
