Answer:
The constant of proportionality is equal to 4
Step-by-step explanation:
The picture of the question in the attached figure
Let
y ----> the total cost in dollars
x ----> the number of bags of peanuts
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
To find out the constant of proportionality, we need to take one point from the graph
take the point (1,4)
Find the value of k
[tex]k=\frac{y}{x}[/tex]
substitute the value of x and the value of y
[tex]k=\frac{4}{1}=\$4\ per bag[/tex]
