At the custard creamery, the cost of ice cream custard is directly proportional to its weight in ounces, complete the equation of the graph with its constant proportionality

Let's assume the cost of ice cream custard is directly proportional to its weight in ounces. We can represent that using the equation:

Cost = k * Weight

Here, k represents the constant proportionality between cost and weight.

To complete the equation of the graph with the constant proportionality (k), we need some additional information.
