At the custard creamery the cost of ice cream is directly proportional to its weight in ounces complete the equation of the graph with it’s constant of proportionality $5 = 2ounces $10= 4 ounces
We can set up a proportion to find the constant of proportionality.
Let the constant of proportionality be $k. Then, we have:
$5 = 2k
Dividing both sides by 2, we find:
k = $2.5
Therefore, the equation of the graph is:
$5 = 2.5 * ounces
