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.
