The instructions say "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."

  • this task is very much like what you did for "total"
  • instead of "total", this time the variable will be named "profitPerUnit"
  • instead of dividing profit by salesTotal, this time you will be dividing the profit by the quantity

Also, you should not replicate any of the number values. So while it may have passed, the assignment of "salesTotal" in task 1 should look like this:

var salesTotal = retailPrice * quantity;
