Write an expression that calculates the total price for all orders. price * total_number Quiz 2.8 #8 : You are given two variables, both already defined, one associated with a float and named total_weight , containing the weight of a ship ment, the other associated with an int and named quantity , containing the number of items in the shipment. Write an expression that calculates the weight of one item. total_weight / quantity Quiz 2.8 #9 : Assume there is a variable, h already assigned a p ositive integer value. Write the code necessary to assign its square to the variable g. For example, if h had the value 8 then g would get the value 64. g = h * h Quiz 2.8 #10 : Assume that price is an integer variable whose value is the price (in US currency) in cents of an item.
