Given the values of $x$ and $y$, find an equation of variation in which $y$ varies directly as $x$.
-$y=3.68$, when $x=1.6$
A) $x=2.3 y$
B) $y=0.43 x$
C) $y=2.3 x$
D) $y=1.6 x$

When $y$ varies directly as $x$, the equation can be written as $y = kx$, where $k$ is the constant of variation. Given $y=3.68$ when $x=1.6$, we find $k$ by dividing $y$ by $x$, which gives $k = \frac{3.68}{1.6} = 2.3$. Therefore, the equation of variation is $y = 2.3x$.
