$k = 1$ Therefore, our equation for the inverse variation is $y = \frac{1}{x}$ or $xy = 1$
Our equation for an inverse variation is $y = \frac{k}{x}$ or $xy = k$. We will use the second form of the equation to solve for k. $0.04\times25 = k$ $1 = k$ So, $k = 1$ Therefore, our equation for the inverse variation is $y = \frac{1}{x}$ or $xy = 1$
