 <translate> If the TV's original price was $500, at the auction, its price increased by 2 / 5 * $500 = $200. The total price at which the TV was sold at the auction is $500 + $200 = $700. The price of the phone also increased at the action, a 40% increase which is 40 / 100 * $400 = $160. The total price that the phone was sold for after the auction is $400 + $160 = $560. In total, the TV and the phone sold for $700 + $560 = $1260 at the auction.
