Answers: 3
![\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of proportionality}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \textit{we know that} \begin{cases} x=3\\ y=45.57 \end{cases}\implies 45.57=k(3)\implies \cfrac{45.57}{3}=k\implies 15.19=k](/tpl/images/2630/9689/71abc.png)
