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

State the number of variables Jack would require in his program. (1)

6 (1 mark)

Also accept 5 as program could formula as…

Profit = Selling Price – (Water Cost + Flavouring Cost + Labour Cost) 

Therefore Manufacturing Cost not required.
