-Stuff Pty Ltd sells stuff. The unit cost of the stuff varies according to the quantity ordered. Customers can order any number of items. ​ Stuff Pty Ltd use this scale: +
-1-9 items = $100 each +
-10-19 items = $97 each +
-20-29 items = $92 each +
-30-39 items = $88 each +
-40-49 items = $85 each +
-50 or more = $82 each +
- +
-Task: using pseudocode, create an algorithm ​to calculate ​the unit cost of the items at different quantities. Then calculate a total cost with 10% GST added. ​  +
-Convert the pseudocode into code. +
-Create test data to fully test all aspects of the solution’s functionality. +
-Note:  Input data need not be validated, and the interface ​can be very basic. +
