I've got a question that ask you to prepare a 10 column work sheet based on the information given, the things I'm confused about is the stock section

The business was brought in 1/06/08 with promotional material supplies $550
On 4/06/08 purchase promotional materials $346
On 15/06/08 purchase promotional materials $479

The end of the year (30/06/09) closing stock of promotional materials is $910

The entry I did is as follows:

4/06/08 Promotional Material Supplies $346 DR
Cash $346 CR
15/06/08 Promotional Material Supplies $479 DR
Cash $479 CR

For the end of the year adjustment entry, to reflect the stock on hand ($910)

30/06/2008 Promotional Material Expense $465 DR
Promotional Material Supplies $465 CR

Can anyone tell me if it is OK?

I think it's but don't keep in that for ever, try to get the best u can
