The answer to the problem is c
It is a ratio problem...
2 dogs need 144 feet = 2 : 144
Simplify the ratio = 1 : 72
Multiply both sides by 8 (8 dogs) = 1*8 :144*8
Simplify the ratio = 8 : 1152
8 dogs need 1152 feet of fencing
Hope this helps!

Answer:
30 is the cost of clothes Kyle bought.
Step-by-step explanation:
Given: Kyle spend 1/5 of his money on clothing.
Remaining money is 120.
Lets assume the total money Kyle had be "x".
∴ Money spent on clothes = ![\frac{1}{5}\times x= \frac{x}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%5Ctimes%20x%3D%20%5Cfrac%7Bx%7D%7B5%7D)
Now, putting up value in the equation to find the total amount of money.
We know, money remaining is 120
![x-\frac{x}{5} = 120](https://tex.z-dn.net/?f=x-%5Cfrac%7Bx%7D%7B5%7D%20%3D%20120)
Taking LCD subtract the fraction.
⇒ ![\frac{(x\times 5)- x\times 1}{5} = 120](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%5Ctimes%205%29-%20x%5Ctimes%201%7D%7B5%7D%20%3D%20120)
⇒ ![\frac{5x-x}{5} = 120](https://tex.z-dn.net/?f=%5Cfrac%7B5x-x%7D%7B5%7D%20%3D%20120)
⇒![\frac{4x}{5} = 120](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B5%7D%20%3D%20120)
Multiplying 5 both side
⇒![4x= 120\times 5](https://tex.z-dn.net/?f=4x%3D%20120%5Ctimes%205)
dividing 4 on both side.
∴![x= \frac{120\times 5}{4}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B120%5Ctimes%205%7D%7B4%7D)
∴ x= 150
Kyle has total 150 money to spend.
Kyle spent
of his total money on clothing.
⇒ cost of clothes kyle bought= ![\frac{1}{5} \times 150= 30](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%5Ctimes%20150%3D%2030)
Hence, Kyle spent 30, which was the cost of clothes kyle bought.
