A school bookshop sells an outdated biology text book for $49.35, making a 6% loss.
What was the cost price of the book, and what is the cash value of the loss?

  X=49.35/0.94=52.5
  LOSS=3.15

• Given: selling price = $49.35,
  loss = 6% of cost price
  but, (cost price) = (selling price) + loss
  Expressing as percentages of the cost price:
  (cost price) = (selling price) + loss
  100% x% + 6%
  This means that the selling price is (100-6) = 94% of the cost price.
  94
  selling price = -------- × (cost price)
  100
  So:
  100
  cost price = -------- × (selling price)
  94
  
  100
  = -------- × 49.35
  94
  = $52.50
  So: loss = (cost price) - (selling price)
  = $52.50 - $49.35
  = $3.15
