you need to do the exercise like the instructions say... its fairly straight forward once you realize that java cast everything to the lowest type used, which is 'int' in this case. ***all calculation values need to be type cast to double (the highest used) the discountprice goes in as an 'int' so you need to type cast the values used to 'double' remember - the discountprice is an 'int' not a percentage... hint - devide by 100 to get the percentage (but your still not done...)
