Hint 4 for Lab 01: changing the outputting of the results

1. Remove two of the output lines.
2. Change the first of the remaining line so that within the ()'s you have "The total interest on the item is "+interest
3. Change the second of the remaining line so that within the ()'s you have "The total cost on the item is "+total
4. Don't worry about not having a '$', not displaying the cents correctly, or round off issues
