So if x people were surveyed, 
people owned a bike and 
did not.
The difference between them is 72:
x-\frac{1}{8} [/tex] =72
so this means that
x=72
let's simplify:
x=72
and divide by 3:
x=24
and mupliply by 4:
x=96
so 96 people were surveyed

<h3>Answer: Choice B. f(x) = 100 - 68x</h3>
Work Shown:
Solve for y. Then replace y with f(x).
Effectively this involves adding 1000 to both sides and subtracting 680x from both sides, afterward we divide both sides by 10 to isolate y.
