Write an menu billing application for the Socialist-Workers cafe located in a tropical town in Australia. The Workers at the cafe all have University degrees in Historical Political Economics from the Faculty of Arts at the North-Western Territories University and are therefore unable to use a calculator. The number of menu items of each type ordered. Naturally the Socialist-Workers Cafe displays cost items without the GST component so the repressive nature of the GST can be highlighted when the Bill is presented. Your application should contain a function that determines the net cost of the above menu items given the number of each item ordered.
Customers can take away their order in environmentally unfriendly styrofoam cups.
In the case of students and low income workers electing to take-away their order they do not receive a discount. Voluntary Contribution to the oppressed film makers. Please note that bills are generally rather small.
