Question

What is the constant of proportionality as shown in the graph? 17,70) Total Cost (in dollars) Boxed Lunches Ordered x and the total cost in dollars of the lunches u is represented by the graph below

Answer 1

Total cost in dollar of the lunches = y

Number of box lunches ordered = x

`\begin{gathered} y=kx \\ \text{where} \\ k=\text{constant of proportionality} \\ x=17 \\ y=70 \\ 70=k*17 \\ k=(70)/(17) \\ k=(70)/(17) \end{gathered}`
