In the case of the custard creamery, if the cost of the ice cream custard is directly proportional to its weight in ounces, we can express this relationship with the equation:
\[ C = k \cdot w \]
Where:
- \( C \) is the cost of the ice cream custard (in dollars, for example)
- \( w \) is the weight of the ice cream custard (in ounces)
- \( k \) is the constant of proportionality (the cost per ounce)
To complete the equation, you need to know the specific value of \( k \). For example, if the cost is $3 per ounce, then:
\[ C = 3 \cdot w \]
In this case, the constant of proportionality \( k \) would be 3. If you have a different amount for \( k \), you can insert that value accordingly.
