Create a variable named salesTotal. Assign it the total of retailPrice multiplied by quantity.

script.js 
const wholesalePrice = 5.45;
const retailPrice = 9.99;
const quantity = 47;
const salesTotal = quantity * retailPrice;

const wholesalePrice = 5.45; const retailPrice = 9.99; const quantity = 47;

const salesTotal = retailPrice * quantity;

Multiplication is commutative, so the order does not matter.

What I used to pass:

script.js 
const wholesalePrice = 5.45;
const retailPrice = 9.99;
const quantity = 47;

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