I am having trouble multiplying an expression. Can someone help?

"Create another variable named profit. It should hold the value of the salesTotal variable minus the wholesalePrice multiplied by the quantity. In other words, if you sold 47 items for 9.99 but only paid 5.45 for each item, how much money did you make?"

This is the question I have been assigned and I am having trouble writing the proper code. Can someone help?

script.js 
var wholesalePrice = 5.45;
var retailPrice = 9.99;
var quantity = 47;
var salesTotal = retailPrice * quantity;
var profit = (salesTotal - wholeSalePrice) * quanity;

Hi Victor, you made a nice effort but you have a couple of syntax errors in your code and you did things the other way around. You didn't spell the 'wholesalePrice' and 'quantity' variables correctly:

//small letter 's' in the 'wholesalePrice' variable and a 't' is missing in the 'quantity' variable
var profit = (salesTotal - wholeSalePrice) * quanity;

The second task in the challenge requested that you 'create another variable named profit. It should hold the value of the salesTotal variable MINUS the wholesalePrice MULTIPLIED by the quantity':

var profit = salesTotal - (wholesalePrice * quantity);

Moving forward ensure you read tasks more meticulously. Happy coding :)
