Answer:
Proportion states that the two ratios or fractions are equal.
Here, y represents the cost of x ounces of blueberries.
As per the given statement:
A fruit stand sells 8-ounce containers of blueberries for $4.00.
then by definition of proportion we have;
[tex]\frac{4}{8} = \frac{y}{x}[/tex]
By cross multiply we get;
[tex]4x = 8y[/tex]
Divide both sides by 8 we get;
[tex]y = \frac{1}{2} x[/tex]
or
[tex]y = 0.5x[/tex]
Therefore, the equation that correctly models this proportional relationship is, y = 0.5x
