Predict shares for chocolate bars

Suppose a store plans to carry Ghiradelli chocolate in all 5 types. What will the shares be between these five chocolates? The store may want to know this so that they can plan their inventory or re-arrange the display to feature the most popular chocolate types.

The chocolate dataset is pre-loaded for you as an mlogit.data object.

Fit the choc_m2 model using mlogit. The first input should be the formula Selection ~ 0 + Brand + Type + Price and the second should be data = chocolate.
Create a data frame that includes 5 chocolate bars that are all Ghirardelli and all priced at $3. The types should be the five types that were tested in the chocolate data. I've started the code for you. You just need to finish defining the prices.
Predict shares using my predict_mnl() function, which is already loaded.
