Set up a proportion. X is the number you're looking for:
![\frac{3}{x}=\frac{4}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%7D%3D%5Cfrac%7B4%7D%7B100%7D)
This relates 3 to x as 4 percent relates to 100. Simplify the 4 and the 100 to 1 and 25, cross multiply, and solve for x:
![\frac{3}{x}=\frac{4}{100}\\\frac{3}{x}=\frac{1}{25}\\(x)(1)=(3)(25)\\x=75](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%7D%3D%5Cfrac%7B4%7D%7B100%7D%5C%5C%5Cfrac%7B3%7D%7Bx%7D%3D%5Cfrac%7B1%7D%7B25%7D%5C%5C%28x%29%281%29%3D%283%29%2825%29%5C%5Cx%3D75)
3 is 4% of 75.
B would B the answer your looking for. No charge for the pun.(;

-3x+y=-2 divide by -1
3x-y=2 answer
Answer:
y = 36x
Step-by-step explanation:
y varies directly with x ,
that is y
x
Let k be constant
=> y = kx
=> 108 = k(3)
=> k = 108/3
=> k = 36
y can be expressed in terms of x as kx or simply 36x . As we found value of constant as 36.
