Jack has been asked to write a program to calculate the potential profit in a soft drinks business. The program will store the costs involved in producing and selling one litre of each drink.
Jack adapts the program to ensure that water cost can only be entered as always greater than or equal to £0.10 and less than or equal to £0.50 per litre.
Complete the table below to show four different examples of test data for water cost and the type of each example. (3)

Jack has been asked to write a program to calculate the potential profit in a soft drinks business. The program will store the costs involved in producing and selling one litre of each drink.
The following calculations will be used to output the profit made for each litre of drink.
Manufacturing Cost = Water Cost + Flavouring Cost + Labour Cost
Profit = Selling Cost – Manufacturing Cost
Using pseudocode or a programming language of your choice, write a program to enter the required data, then calculate and display the profit for the soft drink business. (5)
