Your software company was invited to provide a proposal for a company in Australia. You currently have the cost in US dollars and need to convert the prices to the Australian dollar. 

Write a 2-part program using Ruby, Java®, or Python. 

Part 1: Write a function to gather the following costs from the user (Validation codes for User input checking are required):

• Travel Cost: $9,800
• Hotel Cost: $3,500
• Rental Car Cost: $1,600
• Labor Cost: $15,500 

Part 2: Write a function to convert the costs from United States dollar (USD) to Australian dollar (AUD). Note: Look up the current USD to AUD exchange rate to use in your function. 

Test the program 3 times by providing different costs in USD. 

Provide the code and take a screenshot of the output, then paste the screenshot(s) into a Microsoft® Word document. 

Write a half-page response in the same Microsoft® Word document to address the following:

• Provide a manual for the user explaining how to use the program.
• Explain what type of user input validations you should have. What happens if the user enters a negative number? What happens if the user puts a $ in the input?
