Question

The cost of 5 pounds of vegetables is $7.55. What is the constant of proportionality that relates the cost of dollars, y,

to the number of pounds of vegetables, x?_(Write a numeric value in decimal form. Do not include units)

Answer 1

1.51

Explanation:

`y` = Cost in dollars of vegetables

`x` = Number of pounds of vegetables

`y\propto x`

`\Rightarrow y=kx`

where k = Constant of proportionality

`k=(y)/(x)`

In one case

`y = 7.55\$`

and
`x = 5\ \text{pounds}`

`k=(7.55)/(5)\\\Rightarrow k=1.51`

The constant of proportionality is 1.51.
