Hi,
Lorraine spent 25% of her money on shopping and 2/5th of the remainder on food.
 If she is left with £450, 
what is the amount {{{highlight(x)}}} of money she had before she started spending.
Question states***
   {{{450 = x - .25x - (2/5)*.75x}}}
   {{{450 = x - .25x - .30x}}}
      450 = .45x
      450/.45 = x
       £1000 = x

and
£1000  - £250 - £300 = £450
