i have created a variable 'profitPerUnit' and have to divide the profit by the quantity but its not allowing me to

var profitPerUnit = parseInt (quantity) / parseFloat (profit);

script.js 
var wholesalePrice = 5.45;
var retailPrice = 9.99;
var quantity = 47;
var salesTotal =  parseFloat(retailPrice)* parseInt(quantity);
console.log(salesTotal);

var profit = parseFloat(salesTotal) - parseFloat(wholesalePrice) * parseInt(quantity);
console.log(profit);

var profitPerUnit =  (quantity/profit);

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!
