Let’s see if we can figure this out. At the end of the Start Up section, the Ledger entry should help the student calculate how much operating capital he has left after getting the store ready for business, which includes the beginning inventory. There is a Ledger Example to show how to make that entry, then there is a blank one at the bottom of the page for the student to use for his actual numbers.
When you calculate the first Profit and Loss at the end of January, that calculation should include only the amount spent on additional inventory ordered during January (to replace stock that was sold in orders that month).
Does that help clarify or just muddy the waters more?
