Question

You just returned from a trip. The countries you visited were Jamaica, The Dominican Republic, and Cuba.

You arrived back in the United States with some foreign currency from these countries.

Write a Java program that prompts the user for an amount of each of these foreign currencies. 

The program should convert these combined amounts to the total equivalent number of US Dollars.

The program should then output the result.



Use exchange rates for these currencies as follows:


1 Jamaican Dollar = 0.0069 US $
1 Dominican Peso = 0.017 US $
1 Cuban Peso = 0.042 US $
     

 

The prompts should look like this:


Enter number of Jamaican Dollars :
Enter number of Dominican Pesos :
Enter number of Cuban Pesos :
     

 

The output should be formatted as follows:


US Dollars = $total amount of US Dollars




Hint: 

 

Be very careful with formatting your output.  The number should look like it represents money.

 

System.out.printf( "US Dollars = $%.2f\n" , totalUnitedStatesDollars   );
