Question

Bananas are $.59 a pound what is the constant of proportionality?

Answer 1

`\bf \qquad \qquad \textit{direct proportional variation}\\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array}\\\\ -------------------------------`


`\bf \begin{array}{ccll} \stackrel{\stackrel{x}{lbs}}{bananas}&\stackrel{\stackrel{y}{lbs}}{price}\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 1&0.59(1)\\ 2&0.59(3)\\ 3&0.59(2)\\ 4&0.59(4)\\ x&0.59(x)\\ \end{array}\implies y=\stackrel{k}{\boxed{0.59}}x`
