Pig Latin Translator

What is Pig Latin?

From Wikipedia:

Pig Latin is a language game or argot in which words in English are altered, usually by adding a fabricated suffix or by moving the onset or initial consonant or consonant cluster of a word to the end of the word and adding a vocalic syllable to create such a suffix. The objective is to conceal the words from others not familiar with the rules.

Movie Ticket Kata

First, head here to join our Zoom meeting. It will help me following along while you work through the assignment.

What Are We Building?

Write a program that calculates purchase price for movie tickets using any language you like. It should not be a full-blown web app; it can be a simple class or collection of methods invokable by your test suite. We'll provide you with some requirements, test-cases, and even a sample interface - all you have to do is give us some software.
