```
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.
```

| Classes | Methods | Scenario | Results |
|-------------|----------------------------------------------------|----------------------------------------------------------|-------------------------|
| basketClass | iterate trough Hashmap(String itemName, int price) | if item is in hashmap | get price |
| | | | |
| basketClass | sum itemPrice * amount | multiply the price by the amount of the specific product | output totalItemPrice |
| | | | |
| basketClass | sum totalItemPrice + totalItemPrice | add price of all items and totalItemPrice | output totalPriceBasket |



```
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.
```
