Nov. $1$ Inventory $10$ units @ $$6$ each

$8$ Purchase $100$ units @ $$6\mathrm{.}45$ each

$17$ Purchase $60$ units @ $$6\mathrm{.}30$ each

$25$ Purchase $80$ units @ $$6\mathrm{.}60$ each

The company uses a periodic inventory system. A physical count of merchandise inventory on November $30$ reveals that there are $90$

units on hand. Cost of goods sold under FIFO is

$$576.$

$$1229.$

$$1020.$

$$591.$
