variables

Create one last variable name profitPerUnit. In that variable store the amount of profit you made for each unit. You can calculate this by dividing the profit by the quantity.It keeps saying bummer did you put divide line

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;       // <-------

You need to put the variable names in for the challenge like this:

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

Interestingly enough, the first two challenges will pass without the user passing in the variables. The third challenge, however, fails if the user does not divide the profit variable by the quantity variable.

Hey Samuel,

For this set of challenges, you can actually pass in the variables when doing math.

For the profitPerUnit variable, you want to divide the profit variable by the quantity variable:

var profitPerUnit = profit / quantity

Essentially, the challenge is prompting you to use the variables you created to do the math.
