It is given that the weight of the barbel is given by:
![f(x)=20x+10](https://tex.z-dn.net/?f=f%28x%29%3D20x%2B10)
It says that there are eight pair of weights so x can take values from 0 to 8 and f(x) can take the values as follows:
![\begin{gathered} x=0,f(x)=10 \\ x=1,f(x)=30 \\ x=2,f(x)=50 \\ x=3,f(x)=70 \\ x=4,f(x)=90 \\ x=5,f(x)=110 \\ x=6,f(x)=130 \\ x=7,f(x)=150 \\ x=8,f(x)=170 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D0%2Cf%28x%29%3D10%20%5C%5C%20x%3D1%2Cf%28x%29%3D30%20%5C%5C%20x%3D2%2Cf%28x%29%3D50%20%5C%5C%20x%3D3%2Cf%28x%29%3D70%20%5C%5C%20x%3D4%2Cf%28x%29%3D90%20%5C%5C%20x%3D5%2Cf%28x%29%3D110%20%5C%5C%20x%3D6%2Cf%28x%29%3D130%20%5C%5C%20x%3D7%2Cf%28x%29%3D150%20%5C%5C%20x%3D8%2Cf%28x%29%3D170%20%5Cend%7Bgathered%7D)
So the range is:
![\mleft\lbrace10,30,50,70,90,110,130,150,170\mright\rbrace](https://tex.z-dn.net/?f=%5Cmleft%5Clbrace10%2C30%2C50%2C70%2C90%2C110%2C130%2C150%2C170%5Cmright%5Crbrace)
Option B is correct.

Answer: To figure out the answer, you have to find c, c equals 0 because adding anything from 9 + 1 equaling 0 will get you above the answer, 10. so, 9c + 1 = 10, now lets change the equation to 9c(0) + 1 = 10, c equaling zero would make the most sense because if c equals 0 then you will get 10, the answer.
