+In Implementation A classes:
+CartEntry
+  initialize two instance variables unit_price & quantity.
+ShoppingCart
+  initialize an instance variables with an empty array.
+Order
+  instantiate a new instance of an entry from the Shopping Cart class with instance variable cart.
+  SALES_TAX is a constant  
+Total_Price
+  calculating the total price of each item in the shopping cart.
+
+Implementation B classes
+CartEntry
+   creates a method to calculate the price of all the same items per quantity.
+ShoppingCart
+  Adds the sum of all items purchased.
+Order
+  instantiate an instance of ShoppingCart and calculates the total of the order with sales tax.
+
+I think it is better to have total_price in order because if a calculation changed in shopping cart it would automatically be reflected in order.
+
+I don't believe it does manipulate the instance variable in other classes.
+
+If we were to add a bulk option I would add it to the price method in CartEntry as a conditional.
+
+I think Implementation B has a single responsibility because Implementation A has some classes with zero responsibility.
