Answer:

<h2>No, because both operation don't have a Constant of Proportionality related.</h2>

Step-by-step explanation:

We can see this calculating the Constant of Proportionality in both cases:

$\frac{4.80}{6} = 0.80\\\\\\\frac{22.50}{18} = 1,25$

We can see that, the proportion is not a Constant, which means that costs are not proportional between the number of bottles sold.

No the cost is not proportional to the number sold.

6 bottles divided by $4.80 = .80 each
18 bottles divided by $22.50 = $1.25 each
