Got it right but you're overdoing it. Take out all the type conversions and the challenge will accept your answer just fine.

var salesTotal = retailPrice * quantity;
var profit = salesTotal - wholesalePrice;
var profitPerUnit = quantity / profit;

Javascript actually handles all the type conversions behind the scenes, so you don't have to worry about all that. The exception is when your final answer must be in a certain form.

Bonus, this makes it easier to read your code!
