Trying out lpSum
In this exercise you are making two types (premium and budget) of ice cream, using heavy cream, whole milk, and sugar. One version is a premium version containing more cream than your budget version. You are looking to find the mixture of ingredients that minimizes the total costs of ingredients.
| Ingredient | $/cup |
|---|---|
| Cream | $1.5 |
| Milk | $0.125 |
| Sugar | $0.10 |
Two Python lists called prod_type and ingredient have been created for you, along with a dictionary var_dict containing the decision variables of the model. You can explore them in the console.
