Your question is not clear. I assume the original question was something like "A store that normally sells an item £268 is having a 30% off sale. What is the sale price of the item?" In that case, the calculation you show is correct: the sale price is (0.7)(£268) = £187.60. You do not show where or how the £167.80 came from, so I can't tell you for sure what you did wrong but it looks as if you just transposed the 8 and the 6 when you wrote it down.

hi Philip,
 
this was at work I was supposed to charge someone for 30% off £268 but somehow I ended up charging them £167.80 so think you might be right about switching the 8 and 6
 
many thanks

James, if you want to skip a step, when you take off 30%, you're left with 70%.
 
0.7(268) = 187.6
 
That wouldn't have saved you from switching numbers, but there ya go.
