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 $15= 6 ounces )Complete the cost of ice cream is directly proportional to its weight in ounces
Let's denote the cost of ice cream as C and the weight of ice cream in ounces as W. According to the given information, we can form the following equation:
C = kW
where k is the constant of proportionality.
We can find the value of k by using any of the given data points. For example, let's use the first data point: $5 = 2 ounces.
Substituting the values into the equation:
5 = k * 2
Simplifying:
k = 5/2
So the constant of proportionality is k = 2.5.
The equation can be written as:
C = 2.5W
