A grocery store sells granola in bulk. What is the price per pound for the granola?

Answer:
$2.5
Step-by-step explanation:
By the graph, the price and weight of the granola bulks are related by a line of the form
[tex]y=m\cdot x[/tex]
where y is the cost of the bulk, x is the weight of the bulk and m is the slope of the line. To compute the slope of the line, note that (0,0) and (2,5) are points on the graph, hence
[tex]m=\dfrac{5-0}{2-0}=\dfrac{5}{2}[/tex]
Therefore, the equation of the line giving the cost-weight relation of a bulk is
[tex]y=\dfrac{5}{2} \cdot x[/tex]
and so the price of 1 pound of granola is
[tex]y = \dfrac{5}{2}\cdot 1=\frac{5}{2}=2.5 \quad \text{pounds.}[/tex]
