Joan Miller owns an advertising agency. One of the adjustments her accountant made at the end of July was $360 for unpaid wages of the secretary. Joan Miller might ask, Why go to the trouble of making this adjustment? Why worry about it? Doesn't everything come out in the end, when the secretary is paid in August? Because wages expense in total is the same for the two months, isn't the net income in total unchanged? Give three reasons why adjusting entries can help Joan Miller assess the performance of her business. (Net income was $1,600.)
