Respuesta :

Answer:

1.51

Step-by-step explanation:

[tex]y[/tex] = Cost in dollars of vegetables

[tex]x[/tex] = Number of pounds of vegetables

[tex]y\propto x[/tex]

[tex]\Rightarrow y=kx[/tex]

where k = Constant of proportionality

[tex]k=\dfrac{y}{x}[/tex]

In one case

[tex]y = 7.55\$[/tex]

and [tex]x = 5\ \text{pounds}[/tex]

[tex]k=\dfrac{7.55}{5}\\\Rightarrow k=1.51[/tex]

The constant of proportionality is 1.51.
