profit per unit question.

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.

What am I doing wrong?

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

The variables salesTotal, profit, and profitPerUnit should all be constructed from operations on the three original variables (wholesalePrice, retailPrice, quantity). If you do it that way, it's a lot more simple. Don't hard-code numeric values in any of those parts of the challenge. Each stage of the challenge more or less tells you flat out how to build the statements.
