Percentage difference

[ukphoenix]

This is probably very simple for some but just cant get my head around the solution

If an item costs £300 per 1000 and i sell the item for £280 per 1000 what percentage difference is there between the 2.

Please show workings out if possible as I have other similar problem I need to convert

TIA

Generally it is not considered proper etiquette to post your problems in more than one thread. If you are not sure, just pick the best one in your estimation and say so. Since you showed some work in the other thread,
