-----------------------------\\\\


\bf y=\cfrac{k}{x}\qquad 
\begin{cases}
y=0.2\\
x=0.3
\end{cases}\implies 0.2=\cfrac{k}{0.3}\implies 0.2\cdot 0.3=k
\\\\\\
\textit{thus, the equation will be}\quad y=\cfrac{0.06}{x}

Tracy McKinney is a disc jockey at radio station WMMM. Her annual salary is $52,750. What is her monthly salary?
attashe74 [19]
Okay, so since her annual salary is <span>$52,750 (the amount she gets a year, all twelve months combined) you're trying to find how much she gets monthly. That would mean we would have to divide her annual salary by 12 to find her monthly salary.

</span>$52,750 ÷ 12 = 4,395.8333333333333
<span>
And since that's a (bothersome) repeating decimal, we're going to have to round it. Once rounded, you would get $</span>4,395.83. That is her monthly salary.
