At the end of the year, Balliol Company's accounting records showed that they had 75 items in stock at a FIFO cost of $10 each. These normally sell for $20 each. Due to increased competition, these items can now be sold for only $14 each. What is the amount of an adjustment, if any, that must be made to the value of the inventory at year-end? Enter digits only, with no commas, decimal points, or dollar signs. Type O if no adjustment is needed
