Well, to start off with $137.50 is not an int, so yes, you're program is going to complain when you enter something other than an int that you are asking for.

The exception is coming because the parseFloat method does not know what to do with the $ sign.

Looking at it though, you are parsing a currency string you have just formatted.

Suggestion: don't format the number to do calculations with. Just run the calculation, then you don't NEED to use the parseFloat method.
