# Create one last variable name profitPerUnit. In that variable store the amount of profit you made for each unit. JavaScr

What am I doing wrong. JavaScript challenge.

script.js
var wholesalePrice = 5.45;
var retailPrice = 9.99;
var quantity = 47;
var salesTotal = 9.99 * 47;
var profit = 469.53 - 256.15;
var profitPerUnit = 213.38 / 47;
var profitPerUnit = 4.54;

For future reference, the question was implying the use of variable names opposed to the use of numbers.

Here's what I used:

var salesTotal = retailPrice * quantity;

var profit = salesTotal - wholesalePrice * quantity;

var profitPerUnit = profit/quantity;

What the code challenge is trying to teach you is that you can o arithmetic by using variable names instead of numbers. so for the last challenge it should look like this:

var profitPerUnit = profit / quantity;

and that is all you need to do.

Got it! Thank you so much Jacob!

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