+# Example Domain Model

+```
+As a user,
+So I can find a specific cohort,
+I want to search a list of all cohorts by cohort name.
+```

+# Exercise 1
+Translate the two following user stories into domain models.
+
+## User Story 1
+```
+As a supermarket shopper,
+So that I can pay for products at checkout,
+I'd like to be able to know the total cost of items in my basket.
+```
+
+### Domain Model Suggestion
+
+| Class   | Method                                           | Class Member                           | Result           | 
+|---------|--------------------------------------------------|----------------------------------------|------------------|
+| Basket  | calculateCost(HashMap<String,Integer> priceList) | HashMap<String,Integer> itemQuantities | Total Cost (int) |
+
+## User Story 2
+```
+As an organised individual,
+So that I can evaluate my shopping habits,
+I'd like to see an itemised receipt that includes the name and price of the products
+I bought as well as the quantity, and a total cost of my basket.
+```
+
+### Domain Model Suggestion
+
+| Class  | Method                                            | Class Member                           | Result                                                                                                               |
+|--------|---------------------------------------------------|----------------------------------------|----------------------------------------------------------------------------------------------------------------------|
+| Basket | exportAnalysis(HashMap<String,Integer> priceList) | HashMap<String,Integer> itemQuantities | Itemised Receipt (HashMap<String,int[]> where the int array contains one value for quantity and one value for price) |
