this question doesn't make sense. its says store the price per unit and then divide the price per unit by quantity.

The total profit for this question would be retail - wholesale * quantity then it says divide by quantity. the price per unit what its asking is retail - wholesale ? will give price per unit. No division necessary. Am i reading this wrong?

script.js
var wholesalePrice = 5.45;
var retailPrice = 9.99;
var quantity = 47;
var salesTotal = retailPrice * quantity;
var profit =  salesTotal - (wholesalePrice * quantity);
var pricePerUnit = retailPrice - wholesalePrice;

There are a couple things that need to be changed in your final variable. First, is your variable is incorrect from what the challenge is asking of you.

Secondly, it is asking that you divide the profit by quantity. Like Below.

var profitPerUnit = profit / quantity;

I hope this helps.

Your math is good, and probably an even better solution, but in this challenge they just want to see you use the divide (/) operator. If they were only looking for the result, your approach would be good.

:point_right: But you'd still need to put it in a variable named profitPerUnit, not "pricePerUnit".
