Find an equation of variation in which $y$ varies inversely as $x$ and the following is true.
-$y=0.8$, when $x=0.6$
A) $y=\frac{1.4}{x}$
B) $y=\frac{0.48}{x}$
C) $y=\frac{1.33}{x}$
D) $y=1.33 x$

In an inverse variation, $y = \frac{k}{x}$, where $k$ is the constant of variation. Given $y=0.8$ when $x=0.6$, we find $k$ by multiplying $y$ and $x$, giving $k = 0.8 \times 0.6 = 0.48$. Thus, the equation is $y = \frac{0.48}{x}$.
