Let's assume that the cost of ice cream custard, C, is directly proportional to its weight in ounces, W.
The general equation for direct proportionality is:
C = k * W
Where k is the constant of proportionality.
Therefore, the equation for the graph can be written as:
C = kW
To find the constant of proportionality, we need to know an actual pair of values for the cost and weight of ice cream custard. With that information, we can substitute the values into the equation and solve for k.
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 up proportionality
