Hi, it's always a good idea to use the variables as the values - as you've already created them beforehand. Always try to not repeat yourself when coding - DRY (Don't Repeat Yourself).

I've added the answer below, hope that helps!

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