Hi Qasim!

You do not need to do the math. You can just use the variable names:

var wholesalePrice = 5.45;
var retailPrice = 9.99;
var quantity = 47;
var salesTotal= retailPrice * quantity;
var profit = salesTotal - wholesalePrice * quantity;
var profitPerUnit = profit / quantity;

Hope that helps!

Thanks! :)

The challenge wants you to use the variables you created in your math not the exact totals. i.e. var salesTotals = quantity * retailPrice;
